McKenney Date: Wed, 19 May 2010 06:27:30 +0000 (+0200) Subject: block: remove all rcu head initializations X-Git-Tag: v2.6.35-rc1~442^2~16 X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=f1ac2502e19c59e996242d406fcc60e4c563e8ce block: remove all rcu head initializations Remove all rcu head inits. We don't care about the RCU head state before passing it to call_rcu() anyway. Only leave the "on_stack" variants so debugobjects can keep track of objects on stack.
