Hello Michael, These patches are some kind of brief highlights of the changes to the userfaultfd pages. The changes to userfaultfd functionality are also described at update to Documentation/vm/userfaultfd.txt [1].
In general, there were three major additions: * hugetlbfs support * shmem support * non-page fault events I think we should add some details about using userfaultfd with different memory types, describe meaning of each feature bits and add some text about the new events. I haven't updated 'struct uffd_msg' yet, and I hesitate whether it's description belongs to userfaultfd.2 or ioctl_userfaultfd.2 As for the userfaultfd.7 we've discussed earlier, I believe it would repeat Documentation/vm/userfaultfd.txt in way, so I'm not really sure it is required. -- Sincerely yours, Mike.
