IOWs, I can't tell why you want to change this from the patch description, hence I don't know if the original behaviour was intentional or not. Can you say describe what the overall effect of the change is in the commit description? Cheers, Dave.

Can you say describe what the overall effect of > the change is in the commit description? Hi Dave, I run xfstests for btrfs against SLES11SP2, not upstream kernel. In the seq.full, I can get the messages 'FIEMAP failed with unsupported flags 2' Then I found that the test will run 'filefrag -vx' on btrfs, and '-v' will run FIEMAP_FLAG_XATTR, which is not supported by btrfs yet, at least in 3.8 kernel.

Sure, I understand that. I'm not asking about how it fails - that much is obvious. What I am asking is: - did it ever work? - if it did, why did it start failing? - how long has it been broken for? > With the patch, I can pass the testcase: > ============================================= > 276 8s ... 7s > Ran: 276 > Passed all 1 tests Great, but why did it break in the first place? That's the information that needs to be in the commit message. Indeed, Eric has pointed out to us *exactly* the information that shoul dbe in the commit message. i.e. a description along the lines of: "Commit 05dadc0 ("Btrfs: add fiemap's flag check") added validity checks to the fiemap flags and hence invalid flags are now being rejected. Test 276 passes an invalid fiemap flag to btrfs, and so that test fails since this commit was added." That tells us exactly why the test failed, why the change is necessary, and how long the test has been broken for. Seen another way, it makes me wonder how often anyone runs xfstests on a btrfs dev tree or regression tests their own changes. Cheers, Dave.

xfstests 276: fix error 'FIBMAP: Invalid argument'
Commit 05dadc0 ("Btrfs: add fiemap's flag check") added validity
checks to the fiemap flags and hence invalid flags are now being
rejected. Test 276 passes an invalid fiemap flag to btrfs, and so
that test fails since this commit was added.
Btrfs doesn't support FIEMAP_FLAG_XATTR, which is enabled by -x option
of filefrag, and will fail with
'FIBMAP: Invalid argument'
for 'filefrag -vx'. 'filefrag -vx' fails on btrfs with
'FIEMAP failed with unsupported flags 2'
Remove the '-x' option.

"this issue" must be different, then; same error ("Invalid argument") but it can no longer be due to the -x option to filefrag. There must be some other root cause. Needs investigation on the btrfs side. IOWs, this looks like it could be a regression in btrfs? -Eric > root@debian-i386:/home/zwu/xfstests# git describe > linux-v3.8-122-gdc75401 > root@debian-i386:/home/zwu/xfstests# uname -a > Linux debian-i386 3.10.0-rc2+ #3 SMP Sun May 26 14:04:13 CST 2013 > x86_64 GNU/Linux > root@debian-i386:/home/zwu/xfstests# > > - output mismatch (see /home/zwu/xfstests/results/btrfs/276.out.bad) > --- tests/btrfs/276.out 2013-05-25 15:09:01.000000000 +0000 > +++ /home/zwu/xfstests/results/btrfs/276.out.bad 2013-05-26 > 09:31:49.962876905 +0000 > @@ -1,3 +1,32393 @@ > QA output created by 276 > *** test backref walking > +FIBMAP: Invalid argument > +FIBMAP: Invalid argument > +FIBMAP: Invalid argument > +FIBMAP: Invalid argument > +FIBMAP: Invalid argument > ... > (Run 'diff -u tests/btrfs/276.out > /home/zwu/xfstests/results/btrfs/276.out.bad' to see the entire diff) > [ 3877.215268] device fsid 8367602a-14fa-49eb-aff0-44da1faa3b45 devid > 1 transid 239 /dev/vdb > [ 3877.218417] btrfs: disk space caching is enabled > Ran: btrfs/276 > Failures: btrfs/276 > Failed 1 of 1 tests > > On Wed, Mar 6, 2013 at 2:43 AM, Rich Johnston <rjohnston@sgi.com> wrote: >> This patch has been committed. >> >> --Rich >> >> commit eba3a5206cd7f8df73d6e6dbf2bb0afca677fca8 >> Author: Wang Sheng-Hui <shhuiw@gmail.com> >> Date: Thu Feb 28 02:05:56 2013 +0000 >> >> xfstests 276: fix error 'FIBMAP: Invalid argument' >> >> >> Commit 05dadc0 ("Btrfs: add fiemap's flag check") added validity >> checks to the fiemap flags and hence invalid flags are now being >> rejected.
