Subject: [PATCH 0/2] btrfs: anon_dev related fixes
Date: Thu, 12 Nov 2026 15:56:32 +1030 [thread overview]
Message-ID: <cover.1794461116.git.wqu@suse.com> (raw)
The first one is a Sashiko bug report, that we have a very narrow window
to hit an anon_dev ID leak.
The second one is another small bug related to double freeing the same
anon_dev ID, exposed by LLM.
Qu Wenruo (2):
btrfs: fix anon_dev leak when snapshot creation races with a root read
btrfs: fix double free of anon_dev in btrfs_get_root_ref() on -EEXIST
