| |
Hi Andrew - please apply if you agree on the more effective version
Make the difference between 'make clean' and 'make distclean/mrproper' more explicit. make clean now removes all generated files except .config* and .version. The result is much easier to understand now.
make clean deletes all generated files (except .config* and .version). make mrproper deletes configuration and all temporary files left by patch, editors and the like.
Example output: > make mrproper CLEAN init CLEAN usr CLEAN scripts/kconfig CLEAN scripts CLEAN .tmp_versions include/config CLEAN include/asm-i386/asm_offsets.h include/linux/autoconf.h include/linux/version.h include/asm .tmp_versions CLEAN .version .config
Form the list of files/directories deleted during make clean, removed all references that is no longer relevant for the current kernel.
