[PATCH 5/6] nouveau: return -EBUSY when hmm_range_wait_until_valid fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



-EAGAIN has a magic meaning for non-blocking faults, so don't overload
it.  Given that the caller doesn't check for specific error codes this
change is purely cosmetic.
