I'm trying to compile gentoo sources linux-2.6.30-gentoo. Module build fails with an error, which I found in the log: drivers/md/dm-bbr.c:39:25: error: dm-bio-list.h: No such file or directory I started with no old config and just set everything up in menuconfig. Reproducible: Always
Created attachment 194260 [details] My .config file
All I did was edit that .c file and comment out the #include. And it built. No idea if it'll run.
Please post your `emerge --info' in a comment and the entire output of the make comment in an attachment and then reopen this bug report. Also report which kernel-sources package you are actually using.
Looks like someone else simultaneously reported this bug, and gentoo-sources-2.6.30-r1 was quickly release thereafter with a fix for this.
