Thomas Gleixner c5780e976e [PATCH] Use the correct restart option for futex_lock_pi ... The current implementation of futex_lock_pi returns -ERESTART_RESTARTBLOCK in case that the lock operation has been interrupted by a signal. This results in a return of -EINTR to userspace in case there is an handler for the signal. This is wrong, because userspace expects that the lock function does not return in any case of signal delivery. This was not caught by my insufficient test case, but triggered a nasty userspace problem in an high load application scenario. Unfortunately also glibc does not check for this invalid return value. Using -ERSTARTNOINTR makes sure, that the interrupted syscall is restarted. The restart block related code can be safely removed, as the possible timeout argument is an absolute time value.
