SubjectRe: Getting FS access events

But no, I doubt we'll move _all_ metadata into the page-cache. I
doubt, for example, that we'll find people re-doing all the other
filesystems. So even if ext2 was page-cache only, what about all
the 35 other filesystems out there in the standard sources, never
mind others that haven't been integrated (XFS, ext3 etc..).

Hmm... what about dropping block device per se' and creating a
pseudo-fs (say /dev/blk/) that gives a page-cache view of the
underlying raw devices?

That way older filesystems and tools could use that view of things
until they are moved into the page-cache, and those people without
the dependence of those filesystems can complete forgo all of this?
