This's been detected by testing generic/323 on btrfs, it keeps
producing chaos of checksum errors.
It is because aio-last-ref-held-by-io uses a static buffer that is
been used repeatedly for every io_submit() call, but we'll issue
NUM_IOS(=16) io_sumbit() in a 'for' loop at a time, and when those
data read by aio has not finish its endio(), its memory is likely to
be used in the next io_submit, which ends up data corruption and
numerous checksum errors.
This allocates memory for each io_submit() and generic/323 runs fine
after this.

By closing the file descriptor before calling io_destroy, you pretty
much guarantee that the last put on the ioctx will be done in interrupt
context (during I/O completion). This behavior has unearthed bugs in
the kernel in several different kernel versions, so let's add a test to
poke at it.
The original test case was provided by Matt Cross. He has graciously
relicensed it under the GPL v2 or later so that it can be included in
xfstests. I've modified the test a bit so that it would generate a
stable output format and to run for a fixed amount of time.

cifs.ko supports server-side copy offloads via CIFS_IOC_COPYCHUNK_FILE.
In handling the ioctl, the request is split into a series of
SMB2 FSCTL_SRV_COPYCHUNK wire requests, which may be handled by the SMB
server as a local read/write, or COW clone as is the case for Samba with
vfs_btrfs.

v2: just include xfs/libxfs.h for the conftest prerequisites
commit cc085d770adb in xfsprogs removed some header files that are
included by loggen.c. Add an autoconf test that checks to see whether
xfs_log_format.h is present. If it is, include that instead of the
deprecated headers and add an alias for XFS_TRANS_MAGIC since that
value no longer exists.
With this patch, xfstests builds on both f20 and rawhide (f21) boxes.

While we're at it, fix a bug in do_open. Just because we pass in '0' for
the flags, doesn't mean that this is the initial open. Move the exit(1)
for that case to the caller.

XFS is returning EEXIST rather than ENOTEMPTY for several of
these rename tests. The rename man page says this about the errors:
ENOTEMPTY or EEXIST
newpath is a nonempty directory, that is, contains
entries other than "." and "..".
Which implies that both errors are valid and so the test should pass
in either case.
