This tests the online label ioctl that btrfs has, which has been
recently proposed for XFS.
To run, it requires an updated xfs_io with the label command and a
filesystem that supports it
A slight change here to _require_xfs_io_command as well, so that
tests which simply fail with "Inappropriate ioctl" can be caught in
the common case.

Project quota can work for ext2 & ext3 the same way as for ext4.
Handle them properly as currently the tests just fail because of
unknown prjquota mount option. After this patch, tests will be "not
run" because ext4 driver refuses to use project quota mount options
for "old" fs types.

ext4 had a bug for files with indirect extents where it wrongly

Btrfs has a bug where we can prematurely ENOSPC if we have lots of
orphaned files, i.e., deleted files which are still open. Add a test
which repeatedly creates and deletes a file while keeping all of the
file descriptors open. This should succeed but doesn't on Btrfs
without the fix.

When test on large SCRATCH_DEV, growing a small XFS to huge size is
a horrible thing (e.g grow 128M to 500T) and it doesn't add any more

yes.

This adds a regression test for the following kernel patch:
b4678df184b3 ("errseq: Always report a writeback error once")
This is motivated by some rather odd behavior done by the PostgreSQL
project. The main database writers will offload the fsync calls to a
separate process, which can open files after a writeback error has
already occurred.
This used to work with older kernels that reported the error to only
one fd, but with the errseq_t changes we lost the ability to see
errors that occurred before the open. The above patch restores that
behavior.

The tests _require_test_lsattr, but don't actually use lsattr. They
use chattr +i/-i, so require the appropriate command.
_require_test_lsattr checks the FS_IOC_GETFLAGS ioctl on a directory
and that is not supported in overlayfs. _require_chattr checks the
ioctl on a file, which is supported in overlayfs, so this change
makes the tests run and pass on overlayfs.

The 3 tests that _require_xfs_io_command "flink", actually require
O_TMPFILE support and flink command, but the former is far unlikely
to be missing. The test btrfs/058 doesn't even use the flink
command.
When running these tests on a filesystem that does not support
O_TMPFILE (e.g. overlayfs) the result is not very infomative:
generic/004 1s ... [not run] xfs_io flink failed (old kernel/wrong fs?)
Decouple the requirements for "flink" command and "-T" command line
flag and require the former explicitly in tests that use it.
As a result the report is now more informative:
generic/004 1s ... [not run] O_TMPFILE is not supported

Multiple origin references to the same lower file from upper files
that are not hardlinks will falsely return the same st_ino/st_dev
for two different overlay files and will cause 'diff' to falsely
report that content of files is the same when it is not.
This test checks that overlayfs detects and fails lookup of a
multiply referenced origin.
The check for multiply referenced origin was a by-product of kernel
commit 31747eda41ef ("ovl: hash directory inodes for fsnotify")
