From: Justin Maggard Date: Mon, 16 Nov 2015 21:42:29 +0000 (+1100) Subject: btrfs: test unmount during quota rescan X-Git-Tag: v2022.05.01~2747 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=7be74ad2968f0ef9c9030ecca66cd1e34e64e967;p=users%2Fhch%2Fxfstests-dev.git btrfs: test unmount during quota rescan This test case tests if we are able to unmount a filesystem while a quota rescan is running. Up to now (4.3) this would result in a kernel NULL pointer dereference. Fixed by patch (btrfs: qgroup: exit the rescan worker during umount).
