| |
Due to commit 02a5e0acb3cb85d80d0fe834e366d38a92bbaa22 kernel build is broken if (CONFIG_COMPAT && ! CONFIG_BLOCK):
CC fs/compat_ioctl.o In file included from include/linux/raid/md_k.h:19, from include/linux/raid/md.h:54, from fs/compat_ioctl.c:25: include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:40: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:48: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h:51: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:64: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_merge_: include/linux/raid/../../../drivers/md/dm-bio-list.h:78: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h: In bio_list_: include/linux/raid/../../../drivers/md/dm-bio-list.h:90: error: dereferencing pointer to incomplete type include/linux/raid/../../../drivers/md/dm-bio-list.h:94: error: dereferencing pointer to incomplete type make[1]: *** [fs/compat_ioctl.o] Error 1 make: *** [fs] Error 2
So either revert that commit or better apply the attached patch to fix it.
