These are patches designed to improve system responsiveness and
interactivity with specific emphasis on the desktop, but suitable to
any commodity hardware workload.

Apply to 3.5.x:

Broken out tarball:

Discrete patches:

Latest BFS by itself:


Code blog when I feel like it:

This is a resync from 3.4-ck3. However, the broken out tarballs above also 
include the upgradeable rwlocks patch, and a modification of the global 
runqueue in BFS to use the urwlocks. These are NOT applied in the -ck1 patch, 
but can be applied manually at the  end of the series as indicated by the 
series file. It is currently of no demonstrable performance advantage OR 
detriment in its current state, but is code for future development.
