Subject: [PATCH 0/5] btrfs: fix transaction leaks and crashes during unmount
Date: Mon, 14 Dec 2020 10:10:44 +0000 [thread overview]
Message-ID: <cover.1607940240.git.fdmanana@suse.com> (raw)
From: Filipe Manana <fdmanana@suse.com>
There are some cases where we can leak a transaction and crash during unmount
after remounting the filesystem in RO mode or mounting RO. These issues were
actually being hit by automated tests from the openQA for openSUSE Tumbleweed
(bugzilla https://bugzilla.suse.com/show_bug.cgi?id=1164503).
Filipe Manana (5):
btrfs: fix transaction leak and crash after RO remount caused by
qgroup rescan
btrfs: fix transaction leak and crash after cleaning up orphans on RO
mount
btrfs: fix race between RO remount and the cleaner task
btrfs: add assertion for empty list of transactions at late stage of
umount
btrfs: run delayed iputs when remounting RO to avoid leaking them
