Commit b3cf8b72334fd35ef961869506e5a72ab398bc82 help xfs/288 to
support v5 filesystems testing, but there're still some old
distributions don't support xfs_db write '-d' option, or can't
write values into dir/attr of v5 filesystems.

For compatible with older versions, skip this test on v5 xfs
if xfs_db write can't write v5 XFS dir/attr.

Hi,

Xiao found v1 can't work well on xfsprogs-4.9, due to 'write -d' can't
write vaules into dir/attr of v5 filesystems before xfsprogs-4.13.

Only check "if write command has -d option" is not enough. So I write
a function _require_xfs_db_write_da() to make sure current xfs_db
can write dir/attr (not only on v5, but especially for v5).

Thanks,
Zorro

Just FYI an upcoming change to the attr block verifier in 4.19 will
break this because it rejects hdr.count == 0.  Can you please set this
to 1 instead of 0?

And update the test here?

Sure, I can change the 0 to 1. BTW, does it affect xfs/288? Because xfs/288 set
hdr.count to 0 too.

IIUC, xfs/288 deliberately sets hdr.count to 0 to test how the code
handles the (corrupt) attr header, so that use is fine.

Hmm... sorry I'm confused now, can you show me the patch which will
"rejects hdr.count == 0"?

xfs/288 trys to check how xfs_repair deal with hdr.count=0. If
"write (-d) hdr.count 0" will be rejected directly, that's another issue.
If it won't affect xfs_db "write", why I can't write 0 in this patch?

Hiding this inside a another requires rule is kinda nasty. If the
test already used _require_scratch_nocheck, this will now cause the
test to check the scratch device at the end of the test.

And vice-versa - if you use _require_scratch_nocheck here, it will
break tests that have already called _require_scratch....

Dave.
