The code looks correct, but I think it would be nicer to change 
hrtimer_nanosleep to take a kernel pointer and have all three
callers (common_nsleep, sys_nanosleep and compat_sys_nanosleep)
do the copy_to_user/put_compat_timespec in the caller.

This would also make it possible to get rid of set_fs() in
compat_sys_clock_nanosleep().
