[PATCH v2 00/10] Make ABORT and LUN RESET handling synchronous

[Bart Van Assche <bvanassche@acm.org>]

Hello Martin,

This is a respin of the patch series that makes ABORT and LUN RESET handling
synchronous. Compared to last time when this patch series was posted, the
actual patch that makes task management function handling synchronous has
been split into three patches. That makes the changes easier to follow.
Please consider this patch series for kernel v4.21.

Thanks,

Bart.

Changes compared to v1: restored the __GFP_RETRY_MAYFAIL flag in patch 2/10
  which had been left out accidentally.
