From 16615be18cadf53ee6f8a4f0bdd647f0753421b1 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 17 Sep 2007 10:59:52 +0100 Subject: [GFS2] Clean up journaled data writing This patch cleans up the code for writing journaled data into the log. It also removes the need to allocate a small "tag" structure for each block written into the log. Instead we just keep count of the outstanding I/O so that we can be sure that its all been written at the correct time. Another result of this patch is that a number of ll_rw_block() calls have become submit_bh() calls, closing some races at the same time.
