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

Browse Source 
Pull block fixes from Jens Axboe:
 "Two small (really, one liners both of them!) fixes that should go into
  this series:

   - Request allocation error handling fix for nbd, from Christophe,
     fixing a regression in this series.

   - An oops fix for drbd. Not a regression in this series, but stable
     material. From Richard"

* 'for-linus' of git://git.kernel.dk/linux-block:
  drbd: Fix kernel_sendmsg() usage - potential NULL deref
  nbd: Fix error handling
