[opensuse-kernel] CONFIG_DEBUG_BLOCK_EXT_DEVT in master
[ reposted with opensuse-kernel@ mailinglist added, sorry to those of you who received this twice ... please reply to this instance if possible ] 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.

If that's what it is, the inability of 11.1 and older to handle greater than 15 partitions via libata was a major gripe on the opensuse user list. Greg -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
