This is a note to let you know that I've just added the patch titled btrfs: add block-group tree to lockdep classes to the 6.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: btrfs-add-block-group-tree-to-lockdep-classes.patch and it can be found in the queue-6.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 1a1b0e729d227f9f758f7b5f1c997e874e94156e Mon Sep 17 00:00:00 2001 From: David Sterba <dsterba@xxxxxxxx> Date: Thu, 1 Jun 2023 00:33:01 +0200 Subject: btrfs: add block-group tree to lockdep classes From: David Sterba <dsterba@xxxxxxxx> commit 1a1b0e729d227f9f758f7b5f1c997e874e94156e upstream. The block group tree was not present among the lockdep classes. We could get potentially lockdep warnings but so far none has been seen, also because block-group-tree is a relatively new feature.
