From 4667a0ec32867865fd4deccf834594b3ea831baf Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Mon, 18 Apr 2011 14:18:09 +0100 Subject: GFS2: Make writeback more responsive to system conditions This patch adds writeback_control to writing back the AIL list. This means that we can then take advantage of the information we get in ->write_inode() in order to set off some pre-emptive writeback. In addition, the AIL code is cleaned up a bit to make it a bit simpler to understand. There is still more which can usefully be done in this area, but this is a good start at least.
