Hi all, After merging the net-next tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from drivers/net/wwan/iosm/iosm_ipc_task_queue.c:6: drivers/net/wwan/iosm/iosm_ipc_imem.h:10:10: fatal error: stdbool.h: No such file or directory 10 | #include | ^~~~~~~~~~~ In file included from drivers/net/wwan/iosm/iosm_ipc_protocol.h:9, from drivers/net/wwan/iosm/iosm_ipc_mux.h:9, from drivers/net/wwan/iosm/iosm_ipc_chnl_cfg.h:9, from drivers/net/wwan/iosm/iosm_ipc_imem_ops.c:8: drivers/net/wwan/iosm/iosm_ipc_imem.h:10:10: fatal error: stdbool.h: No such file or directory 10 | #include | ^~~~~~~~~~~ In file included from drivers/net/wwan/iosm/iosm_ipc_protocol.h:9, from drivers/net/wwan/iosm/iosm_ipc_mux.h:9, from drivers/net/wwan/iosm/iosm_ipc_chnl_cfg.h:9, from drivers/net/wwan/iosm/iosm_ipc_imem.c:8: drivers/net/wwan/iosm/iosm_ipc_imem.h:10:10: fatal error: stdbool.h: No such file or directory 10 | #include | ^~~~~~~~~~~ Caused by commit 13bb8429ca98 ("net: wwan: iosm: firmware flashing and coredump collection") interacting with commit 0666a64a1f48 ("isystem: delete global -isystem compile option") from the kbuild tree. I have reverted the kbuild tree commit for today. Please provide a merge resolution patch. -- Cheers, Stephen Rothwell
