A lot of subsystems have separate mailing lists, because the volume on LKML is so high that people miss important stuff all the time. Of course, major announcements should go to LKML. -hpa - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Yet you are not CC patches and anything here, e.g. .23 updates :( I prefer to have kbuild stuff in the public aka lkml. I should reflect this in MAINTAINERS too. I agree that there is much less noise here at kbuild-devel mainly due to the excellent job of mec that filter away all spam. But then many kbuild matters have impact on a lot of people so lkml is the better place.

Seen it to - but were busy with other stuff. If you do a $ make V=2 Then you will notice that kbuild tells you that the .o files are built because they are not listed in $(targets). Reading the commonts in scripts/Kbuild.include it says: "this is most likely a bug in your kbuild file".

[kbuild-devel] arch/i386/boot rebuilt on every compile...
For some reason, everything in arch/i386/boot is rebuilt on every compile. It's not a huge time waster, but it has annoyed people enough that they ask me about it. version.o and setup.elf obviously would, since they contain a version string, but none of the other .o files have any obvious reason for being rebuild, and the .cmd files don't show any dependencies that I would expect to be revved for each revision.
