This is a note to let you know that I've just added the patch titled perf c2c: Fix sorting in percent_rmt_hitm_cmp() to the 5.15-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: perf-c2c-fix-sorting-in-percent_rmt_hitm_cmp.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5ba5be163ffffb0862a10cd4e9251426e40e3ec2 Author: Leo Yan <leo.yan@xxxxxxxxxx> Date: Mon May 30 16:42:53 2022 +0800 perf c2c: Fix sorting in percent_rmt_hitm_cmp() [ Upstream commit b24192a17337abbf3f44aaa75e15df14a2d0016e ] The function percent_rmt_hitm_cmp() wrongly uses local HITMs for sorting remote HITMs. Since this function is to sort cache lines for remote HITMs, this patch changes to use 'rmt_hitm' field for correct sorting.
