| |
timerfd_show() uses a 'struct itimerspec' internally, but that is deprecated because of the time_t overflow and a conflict with the glibc type of the same name that is now incompatible in user space.
Use a pair of timespec64 variables instead as a simple replacement.
As this removes the last use of itimerspec from the kernel, allowing the removal of the definition from the uapi headers along with timespec and timeval later.
