From 8b6dd72a441a683cef7ace93de0a57ced4367f00 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 30 Mar 2009 14:02:36 -0400 Subject: reiserfs: make per-inode xattr locking more fine grained The per-inode locking can be made more fine-grained to surround just the interaction with the filesystem itself. This really only applies to protecting reads during a write, since concurrent writes are barred with inode->i_mutex at the vfs level.
