Test that the filesystem's implementation of the listxattrs system call lists all the xattrs an inode has. This test is motivated by a bug found in btrfs, which is fixed by the following patch for the linux kernel: "Btrfs: fix listxattrs not listing all xattrs packed in the same item" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
