Patch 1 removes some noise from isolation.c Patch 2 adds some information about the housekeeping flags and a short description on what to expect from the HK functions. I would really like some feedback on this one, since I got all that from the flags usage, and maybe I am misreading stuff. In patch 3, I am suggesting making isolcpus have both the _DOMAIN flag and the _WQ flag, so the _DOMAIN flag is not responsible for isolating cpus on workqueue operations anymore. This will avoid AND'ing both those bitmaps every time we need to check for Workqueue isolation, simplifying code and avoiding cpumask allocation in most cases. Maybe I am missing something in this move, so please provide feedback. In patch 4 I use the results from patch 3 and I disallow pcrypt to schedule work in cpus that are not enabled for workqueue housekeeping, meaning there will be less work done in those isolated cpus.
