Subject: [GIT PULL] Block fixes for 3.18-rc2

Hi Linus,

A small collection of fixes for the current kernel. This pull request
contains:

- Two error handling fixes from Jan Kara. One for null_blk on failure to
  add a device, and the other for the block/scsi_ioctl
  SCSI_IOCTL_SEND_COMMAND fixing up the error jump point.

- A commit added in the merge window for the bio integrity bits
  unfortunately disabled merging for all requests if
  CONFIG_BLK_DEV_INTEGRITY wasn't set. Reverse the logic, so that
  integrity checking wont disallow merges when not enabled.

- A fix from Ming Lei for merging and generating too many segments. This
  caused a BUG in virtio_blk.

- Two error handling printk() fixups from Robert Elliott, improving the
  information given when we rate limit.

- Error handling fixup on elevator_init() failure from Sudip Mukherjee.

- A fix from Tony Battersby, fixing up a memory leak in the scatterlist
  handling with scsi-mq.


Please pull!
