Hello,
these are some uffd updates I have pending that looks ready for
merging. vhost-user KVM developement run into a crash so patch 1/6 is
urgent (and simple), the rest is not urgent.
The testcase has been updated to exercise it.
This should apply clean to -mm, and I reviewed in detail all other
userfaultfd patches that are in -mm and they're all great, including
the shmem zeropage addition.
Alexey Perevalov (1):
userfaultfd: provide pid in userfault msg
Andrea Arcangeli (5):
userfaultfd: hugetlbfs: remove superfluous page unlock in VM_SHARED
case
userfaultfd: selftest: exercise UFFDIO_COPY/ZEROPAGE -EEXIST
userfaultfd: selftest: explicit failure if the SIGBUS test failed
userfaultfd: call userfaultfd_unmap_prep only if __split_vma succeeds
userfaultfd: provide pid in userfault msg - add feat union
