Hi all,
This is part of the third revision of an RFC for adding to XFS support
for tracking reverse-mappings of physical blocks to file and metadata;
and support for mapping multiple file logical blocks to the same
physical block, more commonly known as reflinking.
This patchset aims to make xfstests perform more rigorous testing of
the btrfs/XFS file clone, reflink, and dedupe ioctls. There are now
tests of the basic functionality of the three ioctls; tests to ensure
that the filesystem exhibits the expected copy on write semantics;
tests to try to suss out race conditions in the new write paths; tests
to ensure that the ioctls peform basic disk accounting correctly;
tests of the interaction between reflink and the various fallocate
verbs (allocate, punch, collapse, insert zeroes); and some attempts to
test the upper limits of reflinking and ENOSPC behavior. The tests
have been totally rewritten since the last posting to drop FIEMAP
usage; this should enable the tests to cover NFS and CIFS.
Issues:
* I think the race checks for dedupe could be a little sharper at
finding mistakes.
* I started the numbering really high to prevent the tests from
colliding with whatever new tests might arrive; this will require
some intervention to fix.
* I don't have any interesting NFS/CIFS setups for test. :(
If you're going to start using this mess, you probably ought to just
pull from my github trees for kernel[1], xfsprogs[2], and xfstests[3].
They should just work with the btrfs that's in 4.3.
Comments and questions are, as always, welcome.

* [PATCH 02/12] btrfs: move btrfs reflink tests to generic

Move the cp --reflink tests from btrfs/ to generic/ since xfs now
supports that ioctl.

* [PATCH 02/12] btrfs: move btrfs reflink tests to generic
@ 2015-10-07 5:13 ` Darrick J. Wong

From: Darrick J. Wong @ 2015-10-07 5:13 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-ext4, Anna.Schumaker, linux-btrfs, xfs
Move the cp --reflink tests from btrfs/ to generic/ since xfs now
supports that ioctl.

From: Darrick J. Wong @ 2015-10-07 5:13 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-ext4, Anna.Schumaker, linux-btrfs, xfs
Test the operation of the btrfs (and now xfs) reflink and dedupe
ioctls at various file offsets and with matching and nonmatching
files.

* [PATCH 06/12] reflink: test the various fallocate modes

To: david, darrick.wong; +Cc: Anna.Schumaker, linux-ext4, linux-btrfs, fstests, xfs
Check that the variants of fallocate (allocate, punch, zero range,
collapse range, insert range) do the right thing when they're run
against a range of reflinked blocks.

* [PATCH 06/12] reflink: test the various fallocate modes
@ 2015-10-07 5:13 ` Darrick J. Wong
0 siblings, 0 replies; 42+ messages in thread
From: Darrick J. Wong @ 2015-10-07 5:13 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-ext4, Anna.Schumaker, linux-btrfs, xfs
Check that the variants of fallocate (allocate, punch, zero range,
collapse range, insert range) do the right thing when they're run
against a range of reflinked blocks.

To: david, darrick.wong; +Cc: Anna.Schumaker, linux-ext4, linux-btrfs, fstests, xfs
Check that the free block counts seem to be handled correctly in
the reflink operation and subsequent attempts to rewrite reflinked
copies.

* [PATCH 08/12] reflink: test accuracy of free block counts

From: Darrick J. Wong @ 2015-10-07 5:13 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-ext4, Anna.Schumaker, linux-btrfs, xfs
Check that the free block counts seem to be handled correctly in
the reflink operation and subsequent attempts to rewrite reflinked
copies.

run out of space while reflinking a file.

* [PATCH 12/12] reflink: test that CoW writes fail when we're out of space
2015-10-07 5:12 ` Darrick J. Wong

From: Darrick J. Wong @ 2015-10-07 5:14 UTC (permalink / raw)
To: david, darrick.wong; +Cc: Anna.Schumaker, linux-ext4, linux-btrfs, fstests, xfs
Ensure that copy-on-writing a reflinked file when there's no free disk
space reflects the desired ENOSPC back to userspace during the write
call. Tests the buffered IO, direct IO, and mmap write paths.

* [PATCH 12/12] reflink: test that CoW writes fail when we're out of space
@ 2015-10-07 5:14 ` Darrick J. Wong
0 siblings, 0 replies; 42+ messages in thread
From: Darrick J. Wong @ 2015-10-07 5:14 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-ext4, Anna.Schumaker, linux-btrfs, xfs
Ensure that copy-on-writing a reflinked file when there's no free disk
space reflects the desired ENOSPC back to userspace during the write
call. Tests the buffered IO, direct IO, and mmap write paths.

I don't think that's a good test - we need to check if it's supported by
trying it. That'll automatically get us coverage for other file systems
like xfs.
Note that dedup should get it's own feature check, as currently hacking
nfs into this check will also run dedup tests that can't really be
supported.

Good point. I'll throw that in while I rework the tests.

For now you want to use btrfs on the server, as using reflinks on XFS
seems to be a little unstable over NFS.

Any reason the groups are called clone? I don't really have an opinion
on clone vs reflink but given that the xfs_io command is reflink I'd
rather be consistent.
Otherwise I'd say get it merged ASAP, we can still fix up various
details later.

I found a few more bugs in the kernel-side implementation, which might explain
that. I'm about to start working on making CoW less crappy, but I'll push all
the patches out to github. (I wasn't planning on patchbombing again until
December.)

The existing btrfs reflink tests were tagged in the 'clone' group prior to my
patchset.

I'll merge your patch and repost the whole pile of tests. I'm almost ready to
send a pile of updates for the XFS on-disk structure document which add stuff
about the v5 format, rmapbt, and reflink.

Yes, please push your WIP code out as often as possible!
Btw, here is another additional fixup, as two tests were wrongly
tagged as needing reflink instead of dedupe:

Darrick, can you renumber the xfstests against what is currently at
the head of the repo? If both you an Christoph need them working,
you may as well both patch against the main xfstests repo...
