filesystems
Product: File System
Version: 2.5

patch for xfs_admin
Using "xfs_admin -lu" to print both label and UUID of a mounted XFS filesystem
stopped working in xfs_admin version 5.4.0.
Label is correctly printed, but the UUID is missing:
$ sudo xfs_admin -lu /dev/sda
label = "aaa"
Printing only UUID works as expected:
$ sudo xfs_admin -u /dev/sda
UUID = a3367b49-6f3f-4f50-9b34-38b1561da085
Command also works as expected for an unmounted filesystem
$ sudo xfs_admin -lu /dev/sda
label = "aaa"
UUID = a3367b49-6f3f-4f50-9b34-38b1561da085
The bug is caused by this change --
https://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git/commit/?id=3f153e051abccce0c120ade5c08a675a50cecee9
-- xfs_io is now used to print label and xfs_admin exists after printing it.
I'm attaching a simple naive patch for xfs_admin that fixes this issue.
