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 fs/userfaultfd.c | 8 +- include/uapi/linux/userfaultfd.h | 12 ++- mm/hugetlb.c | 2 +- mm/mmap.c | 22 +++-- tools/testing/selftests/vm/userfaultfd.c | 149 +++++++++++++++++++++++++++++-- 5 files changed, 172 insertions(+), 21 deletions(-) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
