Subject: [PATCH v8 6/9] NFSD: Replace idr_for_each_entry_ul in find_one_sb_stid()
Date: Wed, 08 Apr 2026 08:29:56 -0400 [thread overview]
Message-ID: <20260408-umount-kills-nfsv4-state-v8-6-6e02a1d03d60@oracle.com> (raw)
In-Reply-To: <20260408-umount-kills-nfsv4-state-v8-0-6e02a1d03d60@oracle.com>
From: Chuck Lever <chuck.lever@oracle.com>
Replace idr_for_each_entry_ul() with a while loop over
idr_get_next_ul() for consistency with find_one_export_stid(),
added in a subsequent commit.
No change in behavior.
