  • 516dffdcd   [PATCH] Fix get_unmapped_area and fsync for hugetlb shm segments ... Browse Code »

    This patch provides the following hugetlb-related fixes to the recent stacked
    shm files changes:
    - Update is_file_hugepages() so it will reconize hugetlb shm segments.
    - get_unmapped_area must be called with the nested file struct to handle
    the sfd->file->f_ops->get_unmapped_area == NULL case.
    - The fsync f_op must be wrapped since it is specified in the hugetlbfs
    f_ops.

    This is based on proposed fixes from Eric Biederman that were debugged and
    tested by me. Without it, attempting to use hugetlb shared memory segments
    on powerpc (and likely ia64) will kill your box.

  • bf8f972d3   [PATCH] SHM_NORESERVE flags for shmget() ... Browse Code »

    Add SHM_NORESERVE functionality similar to MAP_NORESERVE for shared memory
    segments.

    This is mainly to avoid abuse of OVERCOMMIT_ALWAYS and this flag is ignored
    for OVERCOMMIT_NEVER.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
