The difference with #v11 is a different implementation of mm_lock that guarantees handling signals in O(N). It's also more lowlatency friendly.
Note that mmu_notifier_unregister may also fail with -EINTR if there are signal pending or the system runs out of vmalloc space or physical memory, only exit_mmap guarantees that any kernel module can be unloaded in presence of an oom condition. Either #v11 or the first three #v12 1,2,3 patches are suitable for inclusion in -mm, pick what you prefer looking at the mmu_notifier_register retval and mm_lock retval difference, I implemented and slighty tested both. GRU and KVM only needs 1,2,3, XPMEM needs the rest of the patchset too (4, ...) but all patches from 4 to the end can be deffered to a second merge window. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
