Hi Jens, After merging the block tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/built-in.o: In function `cdrom_sysctl_handler': cdrom_sysctl.c:(.text+0x156d92): undefined reference to `cdrom_mutex' cdrom_sysctl.c:(.text+0x156da0): undefined reference to `cdrom_autoclose' cdrom_sysctl.c:(.text+0x156dae): undefined reference to `cdrom_autoeject' cdrom_sysctl.c:(.text+0x156dbc): undefined reference to `cdrom_debug' cdrom_sysctl.c:(.text+0x156dca): undefined reference to `cdrom_lockdoor' cdrom_sysctl.c:(.text+0x156dd8): undefined reference to `cdrom_check_media_type' cdrom_sysctl.c:(.text+0x156e0b): undefined reference to `cdrom_list' cdrom_sysctl.c:(.text+0x156e37): undefined reference to `cdrom_autoclose' cdrom_sysctl.c:(.text+0x156e57): undefined reference to `cdrom_autoeject' cdrom_sysctl.c:(.text+0x156e77): undefined reference to `cdrom_check_media_type' cdrom_sysctl.c:(.text+0x156ea4): undefined reference to `cdrom_lockdoor' cdrom_sysctl.c:(.text+0x156eb5): undefined reference to `cdrom_list' cdrom_sysctl.c:(.text+0x15702e): undefined reference to `cdrom_mutex' drivers/built-in.o: In function `cdrom_print_info.constprop.0': cdrom_sysctl.c:(.text+0x1570f3): undefined reference to `cdrom_list' cdrom_sysctl.c:(.text+0x157189): undefined reference to `cdrom_list' drivers/built-in.o: In function `cdrom_sysctl_info': cdrom_sysctl.c:(.text+0x1572c3): undefined reference to `cdrom_mutex' cdrom_sysctl.c:(.text+0x1576dc): undefined reference to `cdrom_mutex' drivers/built-in.o: In function `cdrom_sysctl_register': (.text+0x157765): undefined reference to `cdrom_autoclose' drivers/built-in.o: In function `cdrom_sysctl_register': (.text+0x157781): undefined reference to `cdrom_autoeject' drivers/built-in.o: In function `cdrom_sysctl_register': (.text+0x15778e): undefined reference to `cdrom_debug' drivers/built-in.o: In function `cdrom_sysctl_register': (.text+0x15779b): undefined reference to `cdrom_lockdoor' drivers/built-in.o: In function `cdrom_sysctl_register': (.text+0x1577a8): undefined reference to `cdrom_check_media_type' Probably caused by commit d01681d1457c ("cdrom: export sysctl code"). This build has CONFIG_SYSCTL=y, CONFIG_BLK_DEV_IDECD=m, CONFIG_BLK_DEV_SR=m, CONFIG_PARIDE_PCD=m, CONFIG_CDROM_PKTCDVD=m, CONFIG_GDROM=n. I have used the block tree from next-20141110 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
