From 598278bd4808ed81b0e6fa445458a7d549f72a32 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Fri, 11 Jan 2008 13:31:12 -0600 Subject: [PATCH] [GFS2] Remove unneeded i_spin This patch removes a vestigial variable "i_spin" from the gfs2_inode structure. This not only saves us memory (>300000 of these in memory for the oom test) it also saves us time because we don't have to spend time initializing it (i.e. slightly better performance).
