From 6e5c4ea37a99e5b97aba227fc43f3682d4bc0496 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Thu, 3 Dec 2020 08:51:41 -0500 Subject: [PATCH] gfs2: in signal_our_withdraw wait for unfreeze of _this_ fs only Function signal_our_withdraw needs to work on file systems that have been partially frozen. To do this, it called flush_workqueue(gfs2_freeze_wq). This this wrong because it waits for *ALL* file systems to be unfrozen, not just the one we're withdrawing from. It should only wait for the targetted file system to be unfrozen. Otherwise it would wait until ALL file systems are thawed before signaling the withdraw. This patch changes signal_our_withdraw so it calls flush_work() for the target file system's freeze work (only) to be completed.
