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