Date: Thu, 16 Jul 2015 19:53:22 +0800 From: Ming Lei <ming.lei@...onical.com> To: Jens Axboe <axboe@...com>, linux-kernel@...r.kernel.org Cc: Ming Lei <ming.lei@...onical.com> Subject: [PATCH] blk-mq: set default timeout as 30 seconds It is reasonable to set default timeout of request as 30 seconds instead of 30000 ticks, which may be 300 seconds if HZ is 100, for example, some arm64 based systems may choose 100 HZ.
