__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. # # Cc: Andrew Morton # Cc: Thomas Gleixner # Cc: Peter Zijlstra # Fixes: 4426e945df58
