The patch titled Subject: watchdog/core: remove sysctl handlers from public header has been added to the -mm mm-nonmm-unstable branch. Its filename is watchdog-core-remove-sysctl-handlers-from-public-header.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/watchdog-core-remove-sysctl-handlers-from-public-header.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: Thomas WeiÃ?schuh <linux@xxxxxxxxxxxxxx> Subject: watchdog/core: remove sysctl handlers from public header Date: Wed, 06 Mar 2024 07:49:16 +0100 The functions are only used in the file where they are defined. Remove them from the header and make them static. Also guard proc_soft_watchdog with a #define-guard as it is not used otherwise.
