Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "Two fixes in this pull request:

   - The writeback regression fix from Tejun, which has been weeks in
     the making.  This fixes a case where we would sometimes not issue
     writeback when we should have.

   - An older fix for a memory corruption issue in mtip32xx.  It was
     deferred since we wanted a better fix for this (driver should not
     have to handle that case), but given the timing, it's better to put
     the simple fix in for 4.2 release"
