The patch titled Subject: mm/damon/sysfs-schemes: avoid Wformat-security warning on damon_sysfs_access_pattern_add_range_dir() has been added to the -mm mm-unstable branch. Its filename is mm-damon-sysfs-schemes-avoid-wformat-security-warning-on-damon_sysfs_access_pattern_add_range_dir.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-damon-sysfs-schemes-avoid-wformat-security-warning-on-damon_sysfs_access_pattern_add_range_dir.patch This patch will later appear in the mm-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: SeongJae Park <sj@xxxxxxxxxx> Subject: mm/damon/sysfs-schemes: avoid Wformat-security warning on damon_sysfs_access_pattern_add_range_dir() Date: Mon, 10 Mar 2025 09:50:09 -0700 When -Wformat-security is given, compiler warns as a potential security issue on damon_sysfs_access_pattern_add_range_dir() as below: mm/damon/sysfs-schemes.c: In function `damon_sysfs_access_pattern_add_range_dir': mm/damon/sysfs-schemes.c:1503:25: warning: format not a string literal and no format arguments [-Wformat-security] 1503 | &access_pattern->kobj, name); | ^ Fix it by using "%s" as the format and the name as the argument.
