Subject: [PATCH v3 1/1] nfs42: client needs to strip file mode's
suid/sgid bit after ALLOCATE op
Date: Thu, 24 Aug 2023 16:11:47 -0700
From: Dai Ngo <[email protected]>
To: [email protected], [email protected]

The Linux NFS server strips the SUID and SGID from the file mode
on ALLOCATE op.
Modify _nfs42_proc_fallocate to add NFS_INO_REVAL_FORCED to
nfs_set_cache_invalid's argument to force update of the
file mode suid/sgid bit.
