I have a PVR running Fedora 10 with a 250G ext4 filesystem, created when the disto was installed from DVD. The filesystem is used to store OTA HD TV, files on the order of 6-7G, created by an HD HomeRun, an ethernet-based HDTV tuner, capable of creating two files concurrently. I'm running an almost-latest 2.6.27 kernel, from the Fedora binary rpm.

Page to Process ID

I am trying to work on implementing a new caching strategy. I have a list of particular processes I am to manage the cache for. When a page is to be evicted via "shrink_page_list" I want to use that page and obtain the process ID, and see if that ID is in fact one in my to-manage list. Unfortunately, I have not been able to locate a routine to find the mapping between page to process ID.
