Maybe I'm missing something that this patch does along the lines of teaching the code to be RCU-safe.It is the final piece that makes that the case, so I think it's OK to allow oneself a nice subject line? No? :)Just took me longer to figure out if I am missing something important. E.g., "mm: remove unused RCU-unsafe user page table freeing" would have been clearer to me. Anyhow, just stumbled over it, I don't care too much.
Compromise on: mm: now userland pgtable freeing is safe, remove unused bits ?
