The ->list handler is really not useful at all, because we always call btrfs_xattr_generic_list anyway. After this is done find_btrfs_xattr_handler becomes unused, and it becomes obvious that the temporary name buffer allocation isn't needed but we can directly copy into the supplied buffer. Tested with various getfattr -d calls on varying xattr lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
