  • 754661f14   [PATCH] mark struct inode_operations const 1 ... Browse Code »

    Many struct inode_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • d8c76e6f4   [PATCH] r/o bind mount prepwork: inc_nlink() helper ... Browse Code »

    This is mostly included for parity with dec_nlink(), where we will have some
    more hooks. This one should stay pretty darn straightforward for now.

  • 9a53c3a78   [PATCH] r/o bind mounts: unlink: monitor i_nlink ... Browse Code »

    When a filesystem decrements i_nlink to zero, it means that a write must be
    performed in order to drop the inode from the filesystem.

    We're shortly going to have keep filesystems from being remounted r/o between
    the time that this i_nlink decrement and that write occurs.

    So, add a little helper function to do the decrements. We'll tie into it in a
    bit to note when i_nlink hits zero.

  • ba52de123   [PATCH] inode-diet: Eliminate i_blksize from the inode structure ... Browse Code »

    This eliminates the i_blksize field from struct inode. Filesystems that want
    to provide a per-inode st_blksize can do so by providing their own getattr
    routine instead of using the generic_fillattr() function.

    Note that some filesystems were providing pretty much random (and incorrect)
    values for i_blksize.

  • 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)

  • fac92becd   [PATCH] bfs: fix endianness, signedness; add trivial bugfix ... Browse Code »

    * Makes BFS code endianness-clean.

    * Fixes some signedness warnings.

    * Fixes a problem in fs/bfs/inode.c:164 where inodes not synced to disk
    don't get fully marked as clean. Here's how to reproduce it:

    # mount -o loop -t bfs /bfs.img /mnt
    # df -i /mnt
    Filesystem Inodes IUsed IFree IUse% Mounted on
    /bfs.img 48 1 47 3% /mnt
    # df -k /mnt
    Filesystem 1K-blocks Used Available Use% Mounted on
    /bfs.img 512 5 508 1% /mnt
    # cp 60k-archive.zip /mnt/mt.zip
    # df -k /mnt
    Filesystem 1K-blocks Used Available Use% Mounted on
    /bfs.img 512 65 447 13% /mnt
    # df -i /mnt
    Filesystem Inodes IUsed IFree IUse% Mounted on
    /bfs.img 48 2 46 5% /mnt
    # rm /mnt/mt.zip
    # echo $?
    0

    [If the unlink happens before the buffers flush, the following happens:]

    # df -i /mnt
    Filesystem Inodes IUsed IFree IUse% Mounted on
    /bfs.img 48 2 46 5% /mnt
    # df -k /mnt
    Filesystem 1K-blocks Used Available Use% Mounted on
    /bfs.img 512 65 447 13% /mnt

    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!
