The XFS filestreams allocator caches dir inode -> agno mappings in
an MRU mechanism that holds elements in memory for an amount of time
and then cleans up expired elements in the background. The elements
typically held inode pointers without holding a reference to the
associated inode. This means that if the inode is reclaimed before
an expired entry is cleaned up, the MRU reaper can access freed
memory and cause a panic.
Test for this problem by performing continuous filestreams
allocations under short-lived parent directory inodes. This will
produce KASAN use-after-free splats if enabled during the test.

btrfs-progs patch[1] replaced read(2) write(2) with splice(2) and
caused the append-redirect to stop working.
Before:
btrfs send /btrfs/ro_send > /dev/null
At subvol /btrfs/ro_snap
btrfs send /btrfs/ro_send >> /dev/null
At subvol /btrfs/ro_snap

btrfs send /btrfs/ro_send > /dev/null
At subvol /btrfs/ro_snap
btrfs send /btrfs/ro_send >> /dev/null
At subvol /btrfs/ro_snap
ERROR: failed to read stream from kernel: Invalid argument
Further in the test case the line..
btrfs/130
::
_run_btrfs_util_prog send $SCRATCH_MNT/ro_snap > /dev/null 2>&1
which intended to redirect send output to /dev/null, but ended up
append redirect to the $seqres.full file. And so this test case
failed as 'Invalid argument' for sometime now.
Still as append of a btrfs send output doesn't make sense, so fix
the fstests.
Also adds logs going into $seqres.full.

generic/427 fails on Btrfs with a cryptic "pread: Success" message. This
is because an aio pwrite fails with ENOSPC, so the file isn't as long as
we expect it to be. Make sure we check the result of the aio writes and
also print a more explicit message for short reads (which are
technically valid but in practice shouldn't happen for this test case).
Now the test fails with a much more informative "pwrite: No space left
on device".

Current test expects test_lower to fail with:
truncate(test_lower) should have failed
While it is sort of okay to fail like that (the above expectation
basically acknowledges this weirdness in the overlayfs
implementation), it is by no means the only correct behavior: it is
also correct for the test to succeed (i.e. truncation fails with
ETXTBSY).
So add an option to t_truncate_self.c that allows both success and
failure, but obviously not SIGSEGV, which is what a we'd get in a
real failure mode.

Commit 1ddae54555 ("common/rc: add missing 'local' keywords") exposed
a long-hidden bug in generic/304 -- previously we'd set len to 8EiB, but
_pwrite_byte reset it to 1 because the helper clumsily polluted the
caller's variable namespace. Now that's fixed, but we send an 8EiB
dedupe request to the kernel, which on XFS locks up the kernel while
doing this. The point of this test is to demonstrate that one cannot
dedupe the last byte of a (2^63-1) byte file (that's the way the
interface has behaved historically), so start at 64k below that instead
of offset zero.

Pass the -f option to mkfs.f2fs when it appears to support it. This is
required by f2fs-tools v1.9 and later in order to format the filesystem
even when an existing filesystem is detected. But earlier versions did
not accept this option.
mkfs.f2fs doesn't yet have an option to print its version number. So,
to detect a new enough version we grep for -f in the help output. This
also works for mkfs.btrfs, so we switch that over to the same method
rather than grepping for "force overwrite" in the binary.
