[GIT PULL] Btrfs fixes

[Chris Mason]

Hi Linus,

Dave Sterba queued up a few fixes for btrfs.  I have them in my
for-linus-4.10 branch:

These are all over the place.  The tracepoint part of the pull fixes a
crash and adds a little more information to two tracepoints, while the
rest are good old fashioned fixes.

Hi Linus,

I have a few more fixes in my for-linus-4.1 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.1

The first commit is a fix from Filipe for a very old extent buffer reuse
race that triggered a BUG_ON.  It hasn't come up often, I looked through
old logs at FB and we hit it a handful of times over the last year.

The rest are other corners he hit during testing

Filipe Manana (4) commits (+68/-10):
    Btrfs: fix race when reusing stale extent buffers that leads to BUG_ON (+19/-0)
    Btrfs: fix race between block group creation and their cache writeout (+27/-4)
    Btrfs: fix panic when starting bg cache writeout after IO error (+10/-4)
    Btrfs: fix crash after inode cache writeback failure (+12/-2)

Hi Linus,

I have a few more btrfs fixes in my for-linus-4.1 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.1

These range from corners Filipe found in the new free space cache
writeback to a grab bag of fixes from the list.

Omar Sandoval (4) commits (+38/-19):

Please grab my for-linus branch:

Most of these are fixing extent reservation accounting, or corners with
tree writeback during commit.  Josef's set does add a test, which isn't
strictly a fix, but it'll keep us from making this same mistake again.

Hi Linus,

We have a small queue of btrfs fixes in my for-linus branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

None of these are huge, but my commit does fix a regression from 3.18
that could cause lost files during log replay.

This also adds Dave Sterba to the list of Btrfs maintainers.  It doesn't
mean we're doing things differently, but Dave has really been helping

If you have them basically ready, add them to this, I haven't pulled
yet. So I'll just ignore this and wait for another pull request.

Update on this, we've tracked down the crc errors and are doing final
checks on the patches.  Linus are you planning on taking this pull?  If
not I can just fold the new stuff into a bigger request.

Hi,

Any chance to get these in this round?  I think they're good fixes,
a memory leak and a warning fix, both are got from xfstests.

  https://patchwork.kernel.org/patch/1937031/
- Btrfs: fix memory leak on extent map after fsync

[GIT PULL] Btrfs fixes

[Chris Mason]

Hi Linus,

My for-linus branch has our batch of btrfs fixes:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

We've been hammering away at a crc corruption as well, which I was
really hoping to get into this pull.  It isn't nailed down yet, but we
were finally able to get a solid way to reproduce.  The only good
news is it isn't a recent regression.

The most important batch of fixes in here come from Ilya.  They address
a regression Liu Bo found in the balance ioctls for pausing and resuming
a running balance across drives.

Josef's orphan truncate patch fixes an obscure corruption we'd see
during xfstests.

Arne's patches address problems with subvolume quotas.  If the user
destroys quota groups incorrectly the FS will refuse to mount.

The rest are smaller fixes and plugs for memory leaks.

Hi Linus,

My for-linus branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

Has our series of fixes for the next rc.  The biggest batch is from Jan
Schmidt, fixing up some problems in our subvolume quota code and fixing
btrfs send/receive to work with the new extended inode refs.

My git tree is against 3.6, but these were all retested against your
current git.

Jan Schmidt (7) commits (+149/-76):
    Btrfs: don't put removals from push_node_left into tree mod log twice (+7/-2)

Hi everyone,

The for-linus branch in the btrfs git repo has some fixes:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

The big ones here are a memory leak we introduced in rc1, and 
a scheduling while atomic if the transid on disk doesn't match the
transid we expected.  This happens for corrupt blocks, or out of date
disks.

It also fixes up the ioctl definition for our ioctl to resolve logical
inode numbers.  The __u32 was a merging error and doesn't match what we
ship in the progs.

Chris Mason (2) commits (+36/-17):
    Btrfs: avoid sleeping in verify_parent_transid while atomic (+34/-17)
    Btrfs: Add properly locking around add_root_to_dirty_list (+2/-0)

Hi everyone,

The for-linus branch of the btrfs git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

Has our collection of bug fixes.  I missed the last rc because I thought
our patches were making NFS crash during my xfs test runs.  Turns out it
was an NFS client bug fixed by someone else while I tried to bisect it.

All of these fixes are small, but some are fairly high impact.  The
biggest are fixes for our mount -o remount handling, a deadlock due
to GFP_KERNEL allocations in readdir, and a RAID10 error handling bug.

This was tested against both 3.3 and Linus' master as of this morning.

Hi Linus,

My for-linus branch has two commits:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

One is Al's patch in response to my last pull request, but with one small
change to call d_instantiate before trying to log the inode in
btrfs_link.

The other is a double unlock that Dan Carpenter found.  These did get
rebased this morning before I pushed them out, but I reran tests after
the rebase.

Hi everyone,

This pull request is bigger than I wanted it to be, but Josef has
commits in here for some long running ENOSPC bugs in btrfs.  This is
a few weeks of tracing our delalloc reservations from Josef, and then
fixing up the related bugs.

Outside of Josef's patches we have some assorted fixes.  Arne figured
out we were orphaning whole snapshots if you unmounted enough times
while the snapshot was being deleted.

[GIT PULL] Btrfs fixes

[Chris Mason]

Hi everyone,

The for-linus branch of the linux-btrfs repo has some important fixes:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

The most important in the bunch fixes the btrfs cache flushing.  This
one probably explains many of the corruptions that have been reported,
especially on multi-device filesystems.  I had a hard time hitting it
locally, partially because it is much less likely to happen for fsync
based commits and most of my tests used fsyncs to exercise the commit
code.  Ceph users running with -o notreelog were dramatically more
likely to trigger the corruptions.

The problem was that btrfs was triggering cache flushes before the last
copy of the super block, instead of doing them before the first copy.
We also needed to be more careful about getting flushes done to all the
devices in a multi-device FS before writing any of the supers.  To help
verify the new code, I wrote up a writeback-caching elevator, which I
sent posted earlier today for comments/review.

Many thanks to Alexandre Oliva and Arne Jansen for helping nail this
down.

Outside of the cache flushes, we also have a fix from Liu Bo for
corruptions when snapshotting with mount -o inode_cache enabled.

My for-linus branch is still against 3.1, but these were tested on Linus
git as well.

Josef Bacik (3) commits (+90/-42):
    Btrfs: wait on caching if we're loading the free space cache (+81/-41)

[GIT PULL] Btrfs fixes

[Chris Mason]

Hi Linus,

The for-linus branch of the btrfs git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
sha: 8965593e41dd2d0e2a2f1e6f245336005ea94a2c

Has our fixes since rc1.  These are pretty small, for the most part
we're nailing some regressions in the mount error handling code and
tweaking the ENOSPC throttling.

My for-linus tree is against 3.1, but this was tested against 3.2-rc1 as
well.

Hi Chris-

This pull misses the clone reservation fix again... :)

Thanks!

[GIT PULL] Btrfs fixes

[Chris Mason]

Hi everyone,

The for-linus branch of the btrfs tree on github:

Head commit: a66e7cc626f42de6c745963fe0d807518fa49d39
git://github.com/chrismason/linux.git for-linus

Has the following fixes.  for-linus is against rc6, since some of these
are regression fixes for earlier 3.1 btrfs commits.  The most important
of the bunch is Josef's dentry fix, which avoids enoents if we race with
multiple procs hitting on the same inode.  This bug is btrfs-specific,
it came in with his optimization to cache the inode location during
readdir.

Li Zefan (3) commits (+9/-5):
    Btrfs: don't make a file partly checksummed through file clone (+5/-0)
    Btrfs: don't change inode flag of the dest clone file (+0/-1)
    Btrfs: fix pages truncation in btrfs_ioctl_clone() (+4/-4)

Josef Bacik (1) commits (+11/-2):

Hi Chris,

Maybe, any development regarding to the "[BUG] Btrfs: Corrupted root 
filesystem" subjected bug posted by me ?

[GIT PULL] btrfs fixes

[Chris Mason]

Hi everyone,

The for-linus branch of the btrfs-unstable repo:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git for-linus

Has three more fixes.  We're fixing oopsen during space balancing (btrfs
filesystem balance /mnt)) and during device removal.

Dave Sterba also sent in a patch to make /proc/mounts properly match a
few new mount options, which he (correctly I think) considers a
regression fix because it makes it hard for testers/users to verify the
options in a running config.

Josef Bacik (1) commits (+2/-1):
    Btrfs: don't panic if we get an error while balancing V2

David Sterba (1) commits (+11/-0):
    btrfs: add missing options displayed in mount output

Miao Xie (1) commits (+7/-5):
    btrfs: fix oops when doing space balance

[GIT PULL] Btrfs fixes

[Chris Mason]

Hi Linus

The last pull was missing two fixes, which you can find in the
master branch of the btrfs-unstable repo:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git master

Josef's commit helps close another enospc problem, and the other one
fixes an oops where we try to allocate a zero sized extent off the
drive.

Chris Mason (1) commits (+6/-0):
    Btrfs: make sure the chunk allocator doesn't create zero length chunks

Josef Bacik (1) commits (+15/-5):
    Btrfs: fix data enospc check overflow
