The patch titled Subject: kernel/reboot: replace sprintf() with sysfs_emit() has been added to the -mm mm-nonmm-unstable branch. Its filename is kernel-reboot-replace-sprintf-with-sysfs_emit.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/kernel-reboot-replace-sprintf-with-sysfs_emit.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: zhangguopeng <zhangguopeng@xxxxxxxxxx> Subject: kernel/reboot: replace sprintf() with sysfs_emit() Date: Tue, 5 Nov 2024 17:49:41 +0800 As Documentation/filesystems/sysfs.rst suggested, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. No functional change intended.
