From 6b520e0565422966cdf1c3759bd73df77b0f248c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 12 Dec 2011 15:51:45 -0500 Subject: vfs: fix the stupidity with i_dentry in inode destructors Seeing that just about every destructor got that INIT_LIST_HEAD() copied into it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once(); the cost of taking it into inode_init_always() will be negligible for pipes and sockets and negative for everything else. Not to mention the removal of boilerplate code from ->destroy_inode() instances...
