kernel/time/timekeeping.c: In function ‘timekeeping_resume’:
kernel/time/timekeeping.c:577: error: ‘xtime_locks’ undeclared (first
use in this function)
kernel/time/timekeeping.c:577: error: (Each undeclared identifier is
reported only once
kernel/time/timekeeping.c:577: error: for each function it appears
in.)
make[3]: *** [kernel/time/timekeeping.o] Błąd 1
make[2]: *** [kernel/time] Błąd 2


I change:
write_seqlock(&xtime_locks);
to:
write_seqlock(&xtime_lock);

Corrected patch in attachment.

First warning has gone, but still I have this:
