  • The smp_mb() is becaus sync_page() doesn't have PG_locked while it accesses
    page_mapping(page). The comments in the patch (the entire patch is the
    addition of this comment) try to explain further how and why smp_mb() is
    used.

  • Anton Altaparmakov points out:

    - It calls fault_in_pages_readable() which is completely bogus if @nr_segs >
    1. It needs to be replaced by a to be written
    "fault_in_pages_readable_iovec()".

    - It increments @buf even in the iovec case thus @buf can point to random
    memory really quickly (in the iovec case) and then it calls
    fault_in_pages_readable() on this random memory.

  • We will return NULL from filemap_getpage when a page does not exist in the
    page cache and MAP_NONBLOCK is specified, here:

    page = find_get_page(mapping, pgoff);
    if (!page) {
    if (nonblock)
    return NULL;
    goto no_cached_page;
    }

    But we forget to do so when the page in the cache is not uptodate. The
    following could result in a blocking call:

    /*
    * Ok, found a page in the page cache, now we need to check
    * that it's up-to-date.
    */
    if (!PageUptodate(page))
    goto page_not_uptodate;

  • 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!
