Hi all,

the patch series for FCSE with Linux 2.6.37 is available in the
following git repository:
in a branch named fcse-2.6.37
Also available through gitweb here:

This is a forward port of the 2.6.33 v4 patch, a few things have
changed, a few cleanups here and there, while splitting the patch in
several parts. The most notable change is that we no longer restart
cache flushes when they were preempted, it was, in fact, useless.

Also, I noticed that the hackbench test is not the only one in LTP
testsuite to benefit from the speed improvement brought by this patch,
the whole LTP testsuite takes actually 15% less time to execute with the
FCSE patch on.

I think the patch series can be submitted to mainline, at least as a
request for comments. If you end up submitting them after 2.6.38 is out,
then please tell me, and I will rebase on 2.6.38. The most tedious part
of the job was to split the patch in several parts, now that it is done,
we can rebase easily.
