I don't rely on the pte locking in #v7, exactly to satisfy GRU (so far purely theoretical) performance complains. > atomic context. I think we need a general scheme that allows sleeping when Calls are still in atomic context until we change the i_mmap_lock to a mutex under a CONFIG_XPMEM, or unless we boost mm_users, drop the lock and restart the loop at every different mm. In any case those changes should be under CONFIG_XPMEM IMHO given desktop users definitely don't need this (regular non-blocking mmu notifiers in my patch are all what a desktop user need as far as I can tell). > references are invalidates.

GRU will perform the same with #v7 or V8. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
