Subject: [PATCH 0/2] rcu: Fix series of spurious RCU softirqs
Date: Wed, 24 Nov 2010 01:31:11 +0100	[thread overview]
Message-ID: <1290558673-23580-1-git-send-crap-fweisbec@gmail.com> (raw)

Hi,

I've observed some not so unfrequent series of spurious rcu
softirqs, sometimes happening at each ticks for a random
while.

These patches aims at fixing them.

Thanks.

  rcu: Don't chase unnecessary quiescent states after extended grace periods
  rcu: Stop checking quiescent states after grace period completion from remote
