This is a note to let you know that I've just added the patch titled alpha: fix syscall entry in !AUDUT_SYSCALL case to the 5.4-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: alpha-fix-syscall-entry-in-audut_syscall-case.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d43b3e8e2da755d47987f06a4f2ff84b26065afa Author: Al Viro <viro@xxxxxxxxxxxxxxxxxx> Date: Sat Sep 18 18:18:48 2021 -0400 alpha: fix syscall entry in !AUDUT_SYSCALL case [ Upstream commit f7b2431a6d22f7a91c567708e071dfcd6d66db14 ] We only want to take the slow path if SYSCALL_TRACE or SYSCALL_AUDIT is set; on !AUDIT_SYSCALL configs the current tree hits it whenever _any_ thread flag (including NEED_RESCHED, NOTIFY_SIGNAL, etc.) happens to be set.
