Subject[PATCH-v2 11/17] staging/lustre: fix build when CONFIG_UIDGID_STRICT_TYPE_CHECKS is on
Date
kuid_t/kgid_t are wrappered when CONFIG_UIDGID_STRICT_TYPE_CHECKS is on.
Lustre build is broken because we always treat them as plain __u32.
The patch fixes it. Internally, Lustre always use __u32 uid/gid, and
convert to kuid_t/kgid_t when necessary.
