From f8cec157cb7f04cb247786f8776ebfcebd9b61be Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Tue, 7 May 2019 22:35:05 +0200 Subject: blkdebug: Add "none" event Together with @iotypes and @sector, this can be used to trap e.g. the first read or write access to a certain sector without having to know what happens internally in the block layer, i.e. which "real" events happen right before such an access.
