From: Eric Sandeen Date: Tue, 18 Dec 2012 17:03:57 +0000 (-0600) Subject: jbd: don't wake kjournald unnecessarily X-Git-Tag: v3.8-rc4~10^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7e2fb2d7e6a3094473f101ae33dd6431ae6d2ed1;p=pandora-kernel.git jbd: don't wake kjournald unnecessarily Don't send an extra wakeup to kjournald in the case where we already have the proper target in j_commit_request, i.e. that commit has already been requested for commit. commit d9b0193 "jbd: fix fsync() tid wraparound bug" changed the logic leading to a wakeup, but it caused some extra wakeups which were found to lead to a measurable performance regression.
