This is a note to let you know that I've just added the patch titled thermal/tools/tmon: Include pthread and time headers in tmon.h to the 4.9-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: thermal-tools-tmon-include-pthread-and-time-headers-.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d2eaf6b3c1593abb62eb1b91556add090d6b9ea8 Author: Markus Mayer <mmayer@xxxxxxxxxxxx> Date: Sun Jul 17 20:10:39 2022 -0700 thermal/tools/tmon: Include pthread and time headers in tmon.h [ Upstream commit 0cf51bfe999524377fbb71becb583b4ca6d07cfc ] Include sys/time.h and pthread.h in tmon.h, so that types "pthread_mutex_t" and "struct timeval tv" are known when tmon.h references them. Without these headers, compiling tmon against musl-libc will fail with these errors: In file included from sysfs.c:31:0: tmon.h:47:8: error: unknown type name 'pthread_mutex_t' extern pthread_mutex_t input_lock; ^~~~~~~~~~~~~~~ make[3]: *** [<builtin>: sysfs.o] Error 1 make[3]: *** Waiting for unfinished jobs....
