Hi all, After merging the block tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from block/blk-mq-debugfs-zoned.c:7: block/blk-mq-debugfs.h:24:42: error: 'struct blk_mq_hw_ctx' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] 24 | struct blk_mq_hw_ctx *hctx); | ^~~~~~~~~~~~~ block/blk-mq-debugfs.h:25:44: error: 'struct blk_mq_hw_ctx' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] 25 | void blk_mq_debugfs_unregister_hctx(struct blk_mq_hw_ctx *hctx); | ^~~~~~~~~~~~~ block/blk-mq-debugfs.h:32:47: error: 'struct blk_mq_hw_ctx' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] 32 | struct blk_mq_hw_ctx *hctx); | ^~~~~~~~~~~~~ block/blk-mq-debugfs.h:33:50: error: 'struct blk_mq_hw_ctx' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] 33 | void blk_mq_debugfs_unregister_sched_hctx(struct blk_mq_hw_ctx *hctx); | ^~~~~~~~~~~~~ cc1: all warnings being treated as errors I have no idea what has caused this. I have used the block tree from next-20220308 for today. -- Cheers, Stephen Rothwell
