From e3df715501be3329986e5d9dfa9a477f49e7996b Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sat, 28 May 2005 07:47:39 -0400 Subject: [PATCH] [SCSI] Remove unnecessary locking around completion function calls The SCSI ->done() hook should not be called from inside a spinlock. Drivers that do this are mostly cut-n-paste from 2.2.x-era.
