From bbacb395ac5c57290cdfd02389788cbce64c237e Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Fri, 1 Sep 2023 21:39:26 +0200 Subject: gfs2: Remove freeze_go_demote_ok Before commit b77b4a4815a9 ("gfs2: Rework freeze / thaw logic"), the freeze glock was kept around in the glock cache in shared mode without being actively held while a filesystem is in thawed state. In that state, memory pressure could have eventually evicted the freeze glock, and the freeze_go_demote_ok callback was needed to prevent that from happening. With the freeze / thaw rework, the freeze glock is now always actively held in shared mode while a filesystem is thawed, and the freeze_go_demote_ok hack is no longer needed.
