From d7e3c3249ef23b4617393c69fe464765b4ff1645 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Tue, 29 Apr 2008 09:54:39 +0200 Subject: block: add large command support This patch changes rq->cmd from the static array to a pointer to support large commands. We rarely handle large commands. So for optimization, a struct request still has a static array for a command. rq_init sets rq->cmd pointer to the static array.
