This is a note to let you know that I've just added the patch titled atm: hide unused procfs functions 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: atm-hide-unused-procfs-functions.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 2203171efaa44171c131fd9cc8774c9df3d4472a Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Tue May 16 21:45:34 2023 +0200 atm: hide unused procfs functions [ Upstream commit fb1b7be9b16c1f4626969ba4e95a97da2a452b41 ] When CONFIG_PROC_FS is disabled, the function declarations for some procfs functions are hidden, but the definitions are still build, as shown by this compiler warning: net/atm/resources.c:403:7: error: no previous prototype for 'atm_dev_seq_start' [-Werror=missing-prototypes] net/atm/resources.c:409:6: error: no previous prototype for 'atm_dev_seq_stop' [-Werror=missing-prototypes] net/atm/resources.c:414:7: error: no previous prototype for 'atm_dev_seq_next' [-Werror=missing-prototypes] Add another #ifdef to leave these out of the build.
