Top posting.. :( It will not recompile if the .o files are already there and .c files have not been modified. So if you want to recompile all files do make clean or much better make distclean. make distclean will clean everything even your .config file also. But usually when I am working or checking patches for staging I will just do make clean M=drivers/staging , so it will just clean staging and now when you make again it will compile all files in staging which are in your .config. With sparse if you use C=2 then it will recompile even .o files are there, but with C=1 the default behaviour of not compiling will take effect. regard sudip
