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.

this passes on btrfs, _notruns on xfs/ext4 of yore, and passes
on xfs w/ my online label patchset (as long as xfs_io has the new
capability)

Seems this should be 255, otherwise I got failure like:

-label = "MAXLABEL"
+label: Invalid argument

and MAXLEN=255 makes the test pass with btrfs.

Perhaps we can introduce a new helper similar to _require_acl_get_max()
and _notrun the test if current $FSTYP doesn't define a maxlen on
filesystem label?

There're trailing whitespaces in above two lines, I thought they're the
output from xfs_io label command at first, but actually I have to remove
the spaces to make test pass.

Thanks,
Eryu

You are correct, I missed that they exclude the trailing
null from the length.  (Sorry, thought I tested this :( )

Ok, sure.

It might need a filter, this is output from blkid; it might have changed.
I noticed the whitespace as well but IIRC it works here.

Will look into these and fix stuff up.

Thanks!
