From 7e5b92669904c1de13070ab6d8b788eab9d0cf1f Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Wed, 28 Oct 2020 12:03:23 -0500 Subject: [PATCH] gfs2: don't initialize statfs_change inodes in spectator mode Before commit 97fd734ba17e, the local statfs_changeX inode was never initialized for spectator mounts. However, it still checks for spectator mounts when unmounting everything. There's no good reason to lookup the statfs_changeX files because spectators cannot perform recovery. It still, however, needs the master statfs file for statfs calls. This patch adds the check for spectator mounts to init_statfs.
