The newly added kcompactd code introduces multiple build errors: include/linux/compaction.h:91:12: error: 'kcompactd_run' defined but not used [-Werror=unused-function] mm/compaction.c:1953:2: error: implicit declaration of function 'hotcpu_notifier' [-Werror=implicit-function-declaration] This marks the new empty wrapper functions as 'inline' to avoid unused-function warnings, and includes linux/cpu.h to get the hotcpu_notifier declaration. Fixes: 8364acdfa45a ("mm, compaction: introduce kcompactd") Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- I stumbled over this while trying out the mmots patches today for an unrelated reason.
