[PATCH 5.10 0/2] Fix xfs/179 for 5.10 stable

[Guoqing Jiang <guoqing.jiang@linux.dev>]

Hi,

With the two patches applied, xfs/179 can pass in 5.10.188. Otherwise I got

[root@localhost xfstests]# ./check xfs/179
FSTYP         -- xfs (non-debug)

Please review if they are approriate for 5.10 stable.
