This is a note to let you know that I've just added the patch titled s390: appldata depends on PROC_SYSCTL to the 5.13-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: s390-appldata-depends-on-proc_sysctl.patch and it can be found in the queue-5.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e4c710d9a4f8a09d2256ef43d66e3474e1f62902 Author: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Date: Thu May 27 17:24:20 2021 -0700 s390: appldata depends on PROC_SYSCTL [ Upstream commit 5d3516b3647621d5a1180672ea9e0817fb718ada ] APPLDATA_BASE should depend on PROC_SYSCTL instead of PROC_FS. Building with PROC_FS but not PROC_SYSCTL causes a build error, since appldata_base.c uses data and APIs from fs/proc/proc_sysctl.c. arch/s390/appldata/appldata_base.o: in function `appldata_generic_handler': appldata_base.c:(.text+0x192): undefined reference to `sysctl_vals' Fixes: c185b783b099 ("[S390] Remove config options.")
