Frederic Weisbecker a5dec9f82a posix-cpu-timers: Assert task sighand is locked while starting cputime counter ... Starting the process wide cputime counter needs to be done in the same sighand locking sequence than actually arming the related timer otherwise this races against concurrent timers setting/expiring in the same threadgroup. Detecting that the cputime counter is started without holding the sighand lock is a first step toward debugging such situations.
