From 8fe700650ef69a561a1745764aa42252cfee9c19 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 17 Aug 2017 13:13:22 -0700 Subject: [PATCH] skd: Convert explicit skd_request_fn() calls This will make it easier to convert this driver to the blk-mq approach. This patch also reduces interrupt latency by moving skd_request_fn() calls out of the skd_isr() interrupt.
