Description

LFSCK is too noisy about (not) repairing sharded dirs even there was nothing to repair:

00100000:10000000:9.0:1582907058.066997:0:26150:0:(lfsck_striped_dir.c:2190:lfsck_namespace_striped_dir_rescan()) snx11281-MDT0001-osd: namespace LFSCK repair the shard 0 [0x24010cce0:0x376a:0x0] of the striped directory [0x24010ce0d:0x15cd0:0x0] with dangling no/no, rename no/no, llinkea no/no, repair_lmvea no/no: rc = 0

00100000:10000000:9.0:1582907058.067116:0:26150:0:(lfsck_striped_dir.c:2190:lfsck_namespace_striped_dir_rescan()) snx11281-MDT0001-osd: namespace LFSCK repair the shard 1 [0x2000ecd29:0x376b:0x0] of the striped directory [0x24010ce0d:0x15cd0:0x0] with dangling no/no, rename no/no, llinkea no/no, repair_lmvea no/no: rc = 0

"dangling no/no, rename no/no, llinkea no/no, repair_lmvea no/no" indicates there were no errors, so why those messages populate the lustre debug log?
