It does ... convolutedly: linux/fs.h linux/percpu-rwsem.h linux/rcuwait.h linux/sched/signal.h linux/sched/task.h linux/uaccess.h There may be shorter paths to including that file, but that's the one that's actually used according to cpp. fs/inode.c includes linux/mm.h, so it also gets it through linux/pgtable.h x86/include/asm/pgtable.h x86/include/asm/pkru.h x86/include/asm/fpu/xstate.h which is probably not how you think the mm files get uaccess.h, but again, that's the first way that cpp tells me it gets pulled in. Our header files remain a mess. > > Signed-off-by: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx> > > Acked-by: Michal Hocko <mhocko@xxxxxxxx> Thanks!
