Hi Andrea, This is third version of the patch. Modifications since previous versions: (v3 -> v2) - type of ptid now is __u32. As you suggested. (v2 -> v1) - process thread id is provided only when it was requested with UFFD_FEATURE_THREAD_ID bit. - pid from namespace is provided, so locking thread's gettid in namespace and msg.arg.pagefault.ptid will be equal. This patch is based on git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git userfault branch.
