From 5955102c9984fa081b2d570cfac75c97eecf8f3b Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 22 Jan 2016 15:40:57 -0500 Subject: wrappers for ->i_mutex access parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested}, inode_foo(inode) being mutex_foo(&inode->i_mutex). Please, use those for access to ->i_mutex; over the coming cycle ->i_mutex will become rwsem, with ->lookup() done with it held only shared.
