  • 6fe6900e1   mm: make read_cache_page synchronous ... Browse Code »

    Ensure pages are uptodate after returning from read_cache_page, which allows
    us to cut out most of the filesystem-internal PageUptodate calls.

    I didn't have a great look down the call chains, but this appears to fixes 7
    possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in
    ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in
    block2mtd. All depending on whether the filler is async and/or can return
    with a !uptodate page.

  • 090d2b185   [PATCH] read_mapping_page for address space ... Browse Code »

    Add read_mapping_page() which is used for callers that pass
    mapping->a_ops->readpage as the filler for read_cache_page. This removes
    some duplication from filesystem code.

  • 4b6f5d20b   [PATCH] Make most file operations structs in fs/ const ... Browse Code »

    This is a conversion to make the various file_operations structs in fs/
    const. Basically a regexp job, with a few manual fixups

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)

    We've had two instances recently of overflows when doing

    64_bit_value = (32_bit_value << PAGE_CACHE_SHIFT)

    I did a tree-wide grep of `<page_base)

    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!
