  • fe08a9d49   reiserfs: shrink superblock if no xattrs ... Browse Code »

    This makes in-core superblock fit into one cacheline here.

    Before:
    struct dentry * xattr_root; /* 124 4 */
    /* --- cacheline 1 boundary (128 bytes) --- */
    struct rw_semaphore xattr_dir_sem; /* 128 12 */
    int j_errno; /* 140 4 */
    }; /* size: 144, cachelines: 2 */
    /* sum members: 142, holes: 1, sum holes: 2 */
    /* last cacheline: 16 bytes */

    After:
    int j_errno; /* 124 4 */
    /* --- cacheline 1 boundary (128 bytes) --- */
    }; /* size: 128, cachelines: 1 */
    /* sum members: 126, holes: 1, sum holes: 2 */

  • 5065227b4   [PATCH] reiserfs: on-demand bitmap loading ... Browse Code »

    This is the patch the three previous ones have been leading up to.

    It changes the behavior of ReiserFS from loading and caching all the bitmaps
    as special, to treating the bitmaps like any other bit of metadata and just
    letting the system-wide caches figure out what to hang on to.

    Buffer heads are allocated on the fly, so there is no need to retain pointers
    to all of them. The caching of the metadata occurs when the data is read and
    updated, and is considered invalid and uncached until then.

    I needed to remove the vs-4040 check for performing a duplicate operation on a
    particular bit. The reason is that while the other sites for working with
    bitmaps are allowed to schedule, is_reusable() is called from do_balance(),
    which will panic if a schedule occurs in certain places.

    The benefit of on-demand bitmaps clearly outweighs a sanity check that depends
    on a compile-time option that is discouraged.

  • e1fabd3cc   [PATCH] reiserfs: fix is_reusable bitmap check to not traverse the bitmap info array ... Browse Code »

    There is a check in is_reusable to determine if a particular block is a bitmap
    block. It verifies this by going through the array of bitmap block buffer
    heads and comparing the block number to each one.

    Bitmap blocks are at defined locations on the disk in both old and current
    formats. Simply checking against the known good values is enough.

    This is a trivial optimization for a non-production codepath, but this is the
    first in a series of patches that will ultimately remove the buffer heads from
    that array.

  • bd4c625c0   reiserfs: run scripts/Lindent on reiserfs code ... Browse Code »

    This was a pure indentation change, using:

    scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h

    to make reiserfs match the regular Linux indentation style. As Jeff
    Mahoney writes:

    The ReiserFS code is a mix of a number of different coding styles, sometimes
    different even from line-to-line. Since the code has been relatively stable
    for quite some time and there are few outstanding patches to be applied, it
    is time to reformat the code to conform to the Linux style standard outlined
    in Documentation/CodingStyle.

    This patch contains the result of running scripts/Lindent against
    fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the
    code can be made to look better, but I'd rather keep those patches separate
    so that there isn't a subtle by-hand hand accident in the middle of a huge
    patch. To be clear: This patch is reformatting *only*.

    A number of patches may follow that continue to make the code more consistent
    with the Linux coding style.

    Hans wasn't particularly enthusiastic about these patches, but said he
    wouldn't really oppose them either.

    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!
