| |
Hi all,
After merging the tip tree, today's linux-next build (x86_64 allnoconfig) failed like this:
arch/x86/kernel/process.c: In function '__get_wchan': arch/x86/kernel/process.c:950:2: error: implicit declaration of function 'stack_trace_save_tsk' [-Werror=implicit-function-declaration] 950 | stack_trace_save_tsk(p, &entry, 1, 0); | ^~~~~~~~~~~~~~~~~~~~ cc1: some warnings being treated as errors
Caused by commit
bc9bbb81730e ("x86: Fix get_wchan() to support the ORC unwinder")
stack_trace_save_tsk() requires CONFIG_STACKTRACE which is not set for this build.
I have reverted that commit, and commit
42a20f86dc19 ("sched: Add wrapper for get_wchan() to keep task blocked")
which follows it, for today.
