Test that if we punch a hole in a file, with either a range that goes
beyond the file's size or covers a file range that is already a hole,
and that if after we do some buffered write operations that cover
different parts of the hole, no warnings are emmitted in syslog/dmesg
and the file's content is correct after remounting the filesystem.
This test is motivated by a bug in btrfs that is manifested in kernel
4.12-rc1 onwards (the bug existed long time ago but was not so easy
to expose before 4.12-rc1). The btrfs patch that fixes the issue is
titled: "Btrfs: fix invalid extent maps due to hole punching".

_get_scsi_debug_dev is supposed to return a "/dev/$device".
However, in case the scsi device is not mapped to a disk, hence
/dev/sd* doesn't exist, then get_scsi_debug_dev would return only
the "/dev/" string. In generic/108 we check whether return value is
"" and only then consider it a failure. This behavior allows the
test to erroneously consider _get_scsi_debug_dev succeeded even if
it returned a malformed string. Fix this by correctly checking
whether the return value is "/dev/"

From xfsprogs v4.7, mkfs.xfs add respecification detection by
commit 9090e18. Then mkfs will fail and return if we run it
as below:
mkfs.xfs -m crc=1,finobt=1 -m crc=0 ....
Then _scratch_mkfs_xfs can deal with this problem. But for old
xfsprogs ( < v4.7), it replace the first "crc=1" with the second
"crc=0". Then "crc=0,finobt=1" cause a warning, but keep running:
"warning: finobt not supported without CRC support, disabled."
This extra warning breaks the golden image of xfs/288, so filter
it out in case.

When running xfstests on a kernel configured with CONFIG_AIO=n, all
AIO-related tests fail, often due to an error similar to the
following:
error Function not implemented during io_setup
This affected at least the following tests: generic/036,
generic/112, generic/113, generic/198, generic/207, generic/208,
generic/210, generic/211, generic/239, generic/323, generic/427,
xfs/240, xfs/241.
Fix this by enhancing the 'feature' program to allow testing for
asynchronous I/O support, then skipping all AIO-related tests when
AIO is unsupported.
This change is useful because CONFIG_AIO is sometimes disabled to
reduce the kernel's attack surface (e.g. see
https://android-review.googlesource.com/#/c/292158/).

This is to test whether buffered read retry-repair code is able to

This adds a regression test for the following kernel patches:
mm: avoid spurious 'bad pmd' warning messages
dax: Fix race between colliding PMD & PTE entries
The above patches fix two related PMD vs PTE races in the DAX code.
These can both be easily triggered by having two threads reading and
writing simultaneously to the same private mapping, with the key
being that private mapping reads can be handled with PMDs but
private mapping writes are always handled with PTEs so that we can
COW.
Without this 2-patch kernel series, the newly added test will result
in the following errors:

1) _require_fiemap and _require_xfs_io_command "fiemap" do the

the latter, so i feel they should be unified.
2) The number of helpers like this is slowly growing, but it's
easy to simply use _require_xfs_io_command directly and just
specify the command we want to check.
This is just a cleanup for keeping it simple.
