From e3df18983ea090a2e00dd5c2c6167bb431a0e0a2 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Sat, 25 Mar 2006 03:06:53 -0800 Subject: [PATCH] jbd: embed j_commit_timer in journal struct The kjournald timer is currently on the kernel thread's stack and the journal structure points at it. Save a pointer hop by moving the timer into the journal structure.
