Subject: [GIT PULL rcu/urgent] Adjust SRCU auto-expedite default delay
Date: Thu, 27 Apr 2017 13:46:26 -0700 [thread overview]
Message-ID: <20170427204626.GA21594@linux.vnet.ibm.com> (raw)
Hello, Ingo,
This series adds a small change to yesterday's pull request, namely
changing the default value of the srcutree.exp_holdoff kernel boot
parameter from 50 microseconds to 25 microseconds. This change completely
eliminates the performance shortfall that Mike Galbraith observed.
