My apologies. I missed that you were not cc'ed on this thred: https://lore.kernel.org/linux-mm/20200706202615.32111-1-mike.krav...@oracle.com/ As mentioned, there will likely be another revision to the way locking is handled. The new scheme will try to consider performance as is done in the above link. I suggest you wait for next revision. If you do not mind, I will cc you when the new code is posted. -- Mike Kravetz
