Major kernel components of this project includes:

• /proc/filecache interface for querying the pagecache
• prioritized I/O for readahead/read requests

Major user space components of this project includes:

filecache

a tool for /proc/filecache (to show up in the upcoming linux kernel)

bootcache

create/preload/defrag a set of files for some task(i.e. boot)

readahead-fs

readahead a set of files in parallel

When completed, the potential users can be:

• desktop users, general purpose cache preloading
• system boot
• app startup
• dir tree

• user land support of software suspend to disk (swsusp)
• what to drop before suspend
• what to preload after resume

• server adms / kernel developers
• another view of system's file activity
• to explore/control the page cache
