XFS had a regression where inode reclaim in the unlink codepath would
not correctly tear down extended attribute forks where no xattr extents
are present. Add a generic test to create this condition.

The test sets extended attributes on a series of files under ENOSPC
conditions and then verifies that the files can be removed without
syslog warnings or errors.

Seems you missed "_get_available_space" function definition in
common/rc? I got "command not found" error.

Ah, sorry... that is actually part of a previous patch. I meant to point
out that this depends on the following patch due to the use of the new
helper:

http://thread.gmane.org/gmane.comp.file-systems.fstests/834

Sorry for the confusion.

This fails ext2/3 which don't have fallocate(2) support, need
_require_xfs_io_command "falloc".

This blocks ext2/3 from testing but extN just doesn't support 64k xattr
value, we don't lose much test coverage. On the other hand, changing
falloc to pwrite extends test time significantly (2s -> 30+s) and
doesn't gain much benefit.

I see xfs corruption after the test, I think that's expected.

But I just want to point out here that _check_dmesg is unable to detect
the call traces in dmesg now, as the call trace doesn't have "WARNING",
"kernel BUG" etc. keywords that _check_dmesg searches for, we rely on
_check_fimesystems to fail the test.

Yeah, I don't think it's worth that. It runs really quickly now and the
reason behind it is an XFS regression.

The problem should be fixed upstream, though 4.1 might still fail. I
also need to backport the fix now that it's merged. ;)

Good catch, thanks. The failure here is an XFS error as opposed to a
BUG() or warning. I've updated _check_dmesg() to catch "Internal error"
as well.
