Merge branch 'for-linus' of git://git.kernel.dk/linux-2.6-block
* 'for-linus' of git://git.kernel.dk/linux-2.6-block: block: fix blkdev_issue_flush() not detecting and passing EOPNOTSUPP back block: fix shadowed variable warning in blk-map.c block: remove extern on function definition cciss: remove READ_AHEAD define and use block layer defaults make cdrom.c:check_for_audio_disc() static block/genhd.c: proper externs unexport blk_rq_map_user_iov unexport blk_{get,put}_queue block/genhd.c: cleanups proper prototype for blk_dev_init() block/blk-tag.c should #include "blk.h" Fix DMA access of block device in 64-bit kernel on some non-x86 systems with 4GB or upper 4GB memory block: separate out padding from alignment block: restore the meaning of rq->data_len to the true data length resubmit: cciss: procfs updates to display info about many splice: only return -EAGAIN if there's hope of more data block: fix kernel-docbook parameters and files
