Cover letter [PATCH 2.6.9 0/2] new enhanced accounting data collection

In earlier round of discussion, all partipants favored a common layer of accounting data collection.

This is intended to offer common data collection method for various accounting packages including BSD accounting, ELSA, CSA, and any other acct packages that use a common layer of data collection.

This patchset consists of two parts: acct_io and acct_mm. Discussion identified that improved data collection in the area of I/O and Memory are useful to larger systems.

acct_io:
collects per process data on charater read/written in bytes and number of read/write syscalls made.

acct_mm:
collects per process data on rss and vm total usage and peak usage.

Andrew, this new version incorporated feedback from your prior comment.
