From 375e289ea85166c5241c570940e7e7e966c63a9f Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 18 Apr 2012 15:16:33 -0400 Subject: vfs: pull ext4's double-i_mutex-locking into common code We want to do this elsewhere as well. Also catch any attempts to use it for directories (where this ordering would conflict with ancestor-first directory ordering in lock_rename).
