From 09cc9fc7a7c3d872065426d7fb0f0ad6d3eb90fc Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Fri, 8 Jul 2011 14:14:40 +1000 Subject: inode: move to per-sb LRU locks With the inode LRUs moving to per-sb structures, there is no longer a need for a global inode_lru_lock. The locking can be made more fine-grained by moving to a per-sb LRU lock, isolating the LRU operations of different filesytsems completely from each other.
