[0/3] Improved FS_IOC_FSSETXATTR tests

Eryu,

Overlayfs gained support for FS_IOC_FSSETXATTR ioctl in v5.2-rc4
with buggy capability check. The fix is trivial so it should land
upstream soon.

This series adds a generic test to cover the bug in overlayfs v5.2-rc4.
It also adds a proper _require directive to test filesystem support
for FS_IOC_FSSETXATTR and let the tests that use this ioctl require
filesystem support for it.

The only existing generic test that needed this requirement is the
recently added generic/553 copy_range immutable file test. When run on
overlayfs over xfs/ext4/btrfs, generic/553 would fail instead of _notrun
with kernel v5.2-rc3.

But the requirement fix is not only for overlayfs, other filesystems
that support FS_IOC_SETFLAGS but not FS_IOC_FSSETXATTR (e.g. ext2),
need those fixes to _notrun generic/553.

Thanks,
Amir.
