  • 685784aaf   xor: make 'xor_blocks' a library routine for use with async_tx ... Browse Code »

    The async_tx api tries to use a dma engine for an operation, but will fall
    back to an optimized software routine otherwise. Xor support is
    implemented using the raid5 xor routines. For organizational purposes this
    routine is moved to a common area.

    The following fixes are also made:
    * rename xor_block => xor_blocks, suggested by Adrian Bunk
    * ensure that xor.o initializes before md.o in the built-in case
    * checkpatch.pl fixes
    * mark calibrate_xor_blocks __init, Adrian Bunk

  • dd172d72a   dm mpath: rdac ... Browse Code »

    This patch supports LSI/Engenio devices in RDAC mode. Like dm-emc
    it requires userspace support. In your multipath.conf file you must have:

    path_checker rdac
    hardware_handler "1 rdac"
    prio_callout "/sbin/mpath_prio_tpc /dev/%n"

    And you also then must have a updated multipath tools release which
    has rdac support.

  • 26b9f2287   dm: delay target ... Browse Code »

    New device-mapper target that can delay I/O (for testing). Reads can be
    separated from writes, redirected to different underlying devices and delayed
    by differing amounts of time.

  • 16a53ecc3   [PATCH] md: merge raid5 and raid6 code ... Browse Code »

    There is a lot of commonality between raid5.c and raid6main.c. This patches
    merges both into one module called raid456. This saves a lot of code, and
    paves the way for online raid5->raid6 migrations.

    There is still duplication, e.g. between handle_stripe5 and handle_stripe6.
    This will probably be cleaned up later.
