From 1afb20f30151dd4160877c827f5b7203f98627fb Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Fri, 25 Apr 2008 12:26:28 +0200 Subject: block: make rq_init() do a full memset() This requires moving rq_init() from get_request() to blk_alloc_request(). The upside is that we can now require an rq_init() from any path that wishes to hand the request to the block layer. rq_init() will be exported for the code that uses struct request without blk_get_request. This is a preparation for large command support, which needs to initialize struct request in a proper way (that is, just doing a memset() will not work).
