Hi Tejun,
while chasing suspend-to-disk bug in -rc3 with Rafael and Jiri, we have noticed that master has
CONFIG_DEBUG_BLOCK_EXT_DEVT
set for almost all configs. This happened through this commit:
commit 5246824c7ea3313c8e4f42f9b19d9e6f0b51861a Author: Tejun Heo <teheo@suse.de> Date: Fri May 29 14:37:12 2009 +0900
- Update config files to enable DEBUG_BLOCK_EXT_DEVT on all configs except for vanilla and ppc/ps3. - patches.suse/block-add-mangle-devt-switch: block: add genhd.mangle_minor parameter (fate#305584).
What is the reason for having it enabled in non-debug/non-trace kernel configs? Even the changelog of 'block-add-mangle-devt-switch' patch mentions this is basically only for testing environments ...
It used to be only for testing environments, when the kinks were still getting worked out. The real-world application for this is e.g. to allow more than 15 partitions on a ATA device. We actually did receive bug reports about this.
