#     mm/gup: Let __get_user_pages_locked() return -EINTR for fatal signal
#     
#     __get_user_pages_locked() will return 0 instead of -EINTR after commit
#     4426e945df588 ("mm/gup: allow VM_FAULT_RETRY for multiple times") which
#     added extra code to allow gup detect fatal signal faster.
#     
#     Restore the original -EINTR behavior.
