[PATCH] nfs: don't report STATX_BTIME in ->getattr

From: Jeff Layton
Date: Mon Jun 12 2023 - 09:34:13 EST


NFS doesn't properly support reporting the btime in getattr (yet), but
61a968b4f05e mistakenly added it to the request_mask. This causes statx
for STATX_BTIME to report a zeroed out btime instead of properly
clearing the flag.
