This is a note to let you know that I've just added the patch titled ARM: renumber bits related to _TIF_WORK_MASK to the 5.10-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: arm-renumber-bits-related-to-_tif_work_mask.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 191f8453fc99a537ea78b727acea739782378b0d Mon Sep 17 00:00:00 2001 From: Jens Axboe <axboe@xxxxxxxxx> Date: Wed, 4 Jan 2023 07:48:37 -0700 Subject: ARM: renumber bits related to _TIF_WORK_MASK From: Jens Axboe <axboe@xxxxxxxxx> commit 191f8453fc99a537ea78b727acea739782378b0d upstream. We want to ensure that the mask related to calling do_work_pending() is within the first 16 bits. Move bits unrelated to that outside of that range, to avoid spuriously calling do_work_pending() when we don't need to.
