Here's my list of pending patches. Ordering them is getting a bit
difficult as various patches that have been out of a while haven't
been commited yet. Note that some patches require Dave's
[PATCH] xfs: fix race in inode cluster freeing failing to stale inodes
applies first. That patch is a clear candidate for something that
should go to Linus ASAP IHMO.

[-- Type: text/plain, Size: 1772 bytes --]
Allowing writeback from reclaim context causes massive problems with stack
overflows as we can call into the writeback code which tends to be a heavy
stack user both in the generic code and XFS from random contexts that
perform memory allocations.
Follow the example of btrfs (and in slightly different form ext4) and refuse
to write out data from reclaim context. This issue should really be handled
by the VM so that we can tune better for this case, but until we get it
sorted out there we have to hack around this in each filesystem with a
complex writeback path.

[-- Attachment #1: xfs-drop-dmapi-hooks --]
[-- Type: text/plain, Size: 62954 bytes --]
Dmapi support was never merged upstream, but we still have a lot of hooks
bloating XFS for it, all over the fast pathes of the filesystem.
This patch drops over 700 lines of dmapi overhead. If we'll ever get HSM
support in mainline at least the namespace events can be done much saner
in the VFS instead of the individual filesystem, so it's not like this
is much help for future work.

[-- Attachment #1: xfs-log_item_desc-list --]
[-- Type: text/plain, Size: 42277 bytes --]
Currently we track log item descriptor belonging to a transaction using a
complex opencoded chunk allocator. This code has been there since day one
and seems to work around the lack of an efficient slab allocator.
This patch replaces it with dynamically allocated log item descriptors
from a dedicated slab pool, linked to the transaction by a linked list.
This allows to greatly simplify the log item descriptor tracking to the
point where it's just a couple hundred lines in xfs_trans.c instead of
a separate file. The external API has also been simplified while we're
at it - the xfs_trans_add_item and xfs_trans_del_item functions to add/
delete items from a transaction have been simplified to the bare minium,
and the xfs_trans_find_item function is replaced with a direct dereference
of the li_desc field. All debug code walking the list of log items in
a transaction is down to a simple list_for_each_entry.
Note that we could easily use a singly linked list here instead of the
double linked list from list.h as the fastpath only does deletion from
sequential traversal. But given that we don't have one available as
a library function yet I use the list.h functions for simplicity.
[the patch applies ontop of Dave's delayed-logging branch]

[-- Attachment #1: xfs-merge-IOP-remove --]
[-- Type: text/plain, Size: 14794 bytes --]
The unpin_remove item operation instances always share most of the
implementation with the respective unpin implementation. So instead
of keeping two different entry points add a remove flag to the unpin
operation and share the code more easily.

Get rid of the xfs_buf_pin/xfs_buf_unpin/xfs_buf_ispin helpers and opencode
them in their only callers, just like we did for the inode pinning a while
ago. Also remove duplicate trace points - the bufitem tracepoints cover
all the information that is present in a buffer tracepoint.

Currently we need to either call IHOLD or xfs_trans_ihold on an inode when
joining it to a transaction via xfs_trans_ijoin.
This patches instead makes xfs_trans_ijoin usable on it's own by doing
an implicity xfs_trans_ihold, which also allows us to drop the third
argument. For the case where we want to hold a reference on the inode
a xfs_trans_ijoin_ref wrapper is added which does the IHOLD and marks
the inode for needing an xfs_iput. In addition to the cleaner interface
to the caller this also simplifies the implementation.

This code was introduced four years ago in commit
3e57ecf640428c01ba1ed8c8fc538447ada1715b without any review and has
been unused since. Remove it just as the rest of the code introduced
in that commit to reduce that stack usage and complexity in this central
piece of code.

Yup, I agree that we have to do this for the moment. It hasn't
caused any problems in my usual OOM testing, so it seems safe
to do.
Reviewed-by: Dave Chinner <dchinner@redhat.com>
Also worth thinking about is if should be checked in
xfs_vm_releasepage() as well to avoid the same stack issues if it
triggers allocation...
Cheers,
Dave.

Looks pretty good to me, and it runs through QA just fine.
There are still a couple of references to dmapi in comments,
but I don't think that's a big issue.

Looks OK - nothing jumps out at me as being incorrect. I'm still
running QA on it, but it looks good so far.

This looks like it applies on top of my xfs_ifree_cluster() bug fix.

Can't say I'm fond of the xfs_trans_iget() setting of the lock
flags, but that's a small price to pay forthe rest of the cleanup.
So it looks good to me.

That's a fine set of cleanups, Christoph:

I'm still running it through QA. If it survives another day or so
I'll push them all out into my git tree for Alex....

I agree this is a potential problem as well.
I did some QA runs with this thrown in, and it causes massive OOM killer
wreckage in xfstests. I've also cross-checked btrfs and ext4 and
neither one skips ->releasepage from reclaim context.

Did you skip it unconditionally, or only when a transaction was
required?
The scary part is that I've seen stack traces (i.e. most stack used)
through this reclaim path for delalloc conversion even for
allocations that are GFP_NOFS and the only thing saving us from
deadlocks is th PF_FSTRANS check. Even worse is that
shrinker_page_list() will call try_to_release_pages() without
checking whether it's allowed to enter the filesystem or not, so we
can be doing block allocation in places we've specifically told the
memory allocation subsystem not to....
Cheers,
Dave.

xfs_vm_releasepage is mostly a no-op if no transaction is required.
If we have neither delalloc nor unwritten buffer we do not actually
enter xfs_page_state_convert, and ->releasepage also doesn't touch
unampped buffers at all.

s/shrinker_page_list/shrink_page_list/ and
s/try_to_release_pages/try_to_release_page/ above.
shrink_page_list takes the gfp_mask for try_to_release_page from
the scan_control structure passed to it from all the top of the long
callchain. I can't find anobvious bug, but this could cause a lot
more harm.

I agree it should go into 2.6.35. Last I saw on that one, Dave
said he was going to update it, so I was waiting for that. I
now see it's available on his kernel.org tree so I can grab
that and get it in the pipeline to send to Linus soon.
I mentioned to you privately a few weeks ago that I had some concerns
about removing DMAPI support, and had promised to send a note out to
the list to that effect, but regretfully I never did that.
I would like to have a chance to submit an alternative to simply
removing that code. I recognize it sits in the first part of your
patch series, and I will gladly do the work to rearrange them to
put it at the end, in order to give me some time to develop my
proposed change.
Basically what I'd like to do is update the DMAPI support code
so that it is much better isolated. I would like to replace
the big ugly hunks that lie in common code paths with small
function calls, so that their footprint is minimal and not
distracting (along the lines of tracing calls).
I got a start on doing this, and had hoped to send the result
pretty soon after your initial posting of the patch, but that
work unfortunately got preempted by other more pressing stuff.
I wanted to provide actual code to help make the discussion
of the merits of removal versus cleanup more concrete. I
now think I'll be able to put something together within the
next week or so.
I'll wait to hear back from you and others. In the mean time
I'll make my way through the rest of the patch series.
-Alex

I don't think it's a good idea. I'm happy to not burn all bridges
and leave certain code structured in a way that makes adding it easier,
but if the hooks are as easy as you say above they can easily live in
an out of tree patchset. The general Linux kernel policy is that we
don't keep hooks for out of tree code around, and I tend to agree to
it. We kept all that dmapi cruft in, and it's never served any
purpose for us. I think that HSM support is actually a very useful
feature, but the a kernel interface based on the DMAPI specification
much less so, and the horrible SGI implementation that used to be
in the XFS CVS tree even less so.
If you want to push a new one the metadata hooks really need to be
entirely outside the low-level filesystem, that is before calling
into the namespace inode operations, which is easily doable even
while keeping the current DMAPI core.
But what's much more difficult is the read/write path. The dmapi
code really gets in the way there, and I have additional simplification
of this code pending that require this cruft to go away. XFS currently
has a needlessly complicated write path, and getting closer to the
generic code will help us with lots of things like the upcoming multi
page write support.

Regardless of the implementation cruftiness, I think this a much
better approach. The events and checks really aren't XFS specific,
and putting them at a higher level cleanly separates the filesystem
functionality from the event+blocking functionality of DMAPI.

That is true, and also intervening higher up in the IO path for
DMAPI would avoid a lot of the locking complexity that XFS has to go
through now to be able to block on events in dmapi calls.
Further, with ext4 gaining a persitent handle interface, adding
DMAPI to the VFS would also enable HSMs to work on more than just
XFS...
Cheers,
Dave.
