From 71fe07d040626de7b72244bf6de889c2e0f5aea3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 4 Oct 2013 06:49:11 -0700 Subject: block: remove request ref_count This reference count has been around since before git history, but the only place where it's used is in blk_execute_rq, and ther it is entirely useless as it is incremented before submitting the request and decremented in the end_io handler before waking up the submitter thread.
