From 5c33b183a36500a5b0a3c53c11c431f0fec6efc8 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 20 Jul 2012 23:05:59 +0400 Subject: uninline file_free_rcu() What inline? Its only use is passing its address to call_rcu(), for fuck sake!

So make mnt_want_write() and mnt_drop_write() (and their _file alternative) prevent freezing as well. For the few cases that are really interested only in remount-ro protection provide new function variants. BugLink: https://bugs.launchpad.net/bugs/897421 Tested-by: Kamal Mostafa Tested-by: Peter M.
