This is a note to let you know that I've just added the patch titled
btrfs: move the printk helpers out of ctree.h
to the 6.1-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-move-the-printk-helpers-out-of-ctree.h.patch
and it can be found in the queue-6.1 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.
commit f8285fa41bee4b2346a277ca6da37205d2f81e7e
Author: Josef Bacik <josef@xxxxxxxxxxxxxx>
Date: Wed Oct 19 10:50:49 2022 -0400
btrfs: move the printk helpers out of ctree.h
[ Upstream commit 9b569ea0be6fb27a4985acc9325896a3edc95ede ]
We have a bunch of printk helpers that are in ctree.h. These have
nothing to do with ctree.c, so move them into their own header.
Subsequent patches will cleanup the printk helpers.
