[PATCH RFC 3/3] dm: add support for REQ_NOWAIT and enable for target dm-linear

Add dm target feature flag DM_TARGET_NOWAIT which tells that target has no problem with REQ_NOWAIT. Set limits.nowait_requests if all targets and backends handle REQ_NOWAIT. Signed-off-by: Konstantin Khlebnikov --- drivers/md/dm-linear.c|5 +++-- drivers/md/dm-table.c |

[PATCH RFC 1/3] block: add flag 'nowait_requests' into queue limits

Add flag for marking bio-based queues which support REQ_NOWAIT. Set for all request based (mq) devices. Stacking device should set it after blk_set_stacking_limits() if method make_request() itself doesn't delay requests or handles REQ_NOWAIT. Signed-off-by: Konstantin Khlebnikov ---

[PATCH RFC 2/3] md/raid0: enable REQ_NOWAIT

[PATCH RFC 0/3] block: allow REQ_NOWAIT to some bio-based/stacked devices

Here is pretty straight forward attempt of handling REQ_NOWAIT for bio-based and stacked devices. They are marked with flag queue->limits.nowait_requests which tells that queue method make_request() handles REQ_NOWAIT or doesn't delay requests, and all backend devices do the same. As a example

[PATCH v2] selftests/seccomp: use 90s as timeout

As seccomp_benchmark tries to calibrate how many samples will take more than 5 seconds to execute, it may end up picking up a number of samples that take 10 (but up to 12) seconds. As the calibration will take double that time, it takes around 20 seconds. Then, it executes the whole thing again,
