[PATCH] posix-timers: Fix clock_nanosleep() doesn't return the remaining time in compatibility mode
The clock_nanosleep() function does not return the time remaining when the
sleep is interrupted by a signal.
This patch creates a new call out, compat_clock_nanosleep_restart(), which
handles returning the remaining time after a sleep is interrupted. This
patch revives clock_nanosleep_restart(). It is now accessed via the new
call out. The compat_clock_nanosleep_restart() is used for compatibility
access.
Since this is implemented in compatibility mode the normal path is
virtually unaffected - no real performance impact.
