Module Name: src
Committed By: dholland
Date: Mon Jan 11 01:08:09 UTC 2016
Modified Files:
src/sys/sys: buf.h
Log Message:
Divide the list of struct buf ops into three categories:
the ones that are part of bufferio(9) (or physio(9))
the ones that are part of buffercache(9)
the ones that aren't documented and thus aren't clear yet
