Coding style violation: if a linux/foo.h exists then it must be included in preference to asm/foo.h And the specific issue is that a follow-up patch moves code from asm/mman.h to linux/mman.h so if any one was indirectly using this header it will now miss the symbols that are being moved. > > > > Signed-off-by: Michael S.
