Subject: [GIT PULL rcu/urgent] Prevent RCU callbacks from executing during early boot
Date: Mon, 11 Jul 2011 09:35:30 -0700 [thread overview]
Message-ID: <20110711163530.GA6329@linux.vnet.ibm.com> (raw)
Hello, Ingo,
This pull request fixes a rare but real boot-time hang. It defers RCU
callback execution until the scheduler has initialized, permitting
RCU callbacks that use late-initialized kernel features to be used in
RCU callbacks that are registered during early boot. This fixes the
bugzilla at: https://bugzilla.kernel.org/show_bug.cgi?id=38732
This commit is available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/urgent
Thanx, Paul
