Subject: AIM7 40% regression with 2.6.26-rc1
Date: Monday, May 5, 2008 - 10:48 pm

Comparing with kernel 2.6.25, AIM7 (use tmpfs) has more than 40% with 2.6.26-rc1
on my 8-core stoakley, 16-core tigerton, and Itanium Montecito. Bisect located
below patch.

64ac24e738823161693bf791f87adc802cf529ff is first bad commit
commit 64ac24e738823161693bf791f87adc802cf529ff
Author: Matthew Wilcox <matthew@wil.cx>
Date:   Fri Mar 7 21:55:58 2008 -0500

    Generic semaphore implementation


After I manually reverted the patch against 2.6.26-rc1 while fixing lots of
conflictions/errors, aim7 regression became less than 2%.
