| 7 | # DESCRIPTION 'ksum.py' generates a combined summary of vmlinux and | ||
| 8 | # module sizes for a built kernel, as a quick tool for comparing the | ||
| 9 | # overall effects of systemic tinification changes. Execute from the | ||
| 10 | # base directory of the kernel build you want to summarize. Setting | ||
| 11 | # the 'verbose' flag will display the sizes for each file included in | ||
| 12 | # the summary. | ||
