kbuild: add option for stripping modules while installing them
Add option for stripping modules while installing them. This function adds support for stripping modules while they are being installed. CONFIG_DEBUG_KERNEL (which will probably become more popular as developers use kdump) causes the size of the installed modules to grow by a factor of 9 or so. Some kernel package systems solve this problem by stripping the debug information from /lib/modules after running "make modules_install", but that may not work for people who are installing directly into /lib/modules --- root partitions that were sized to handle 16 megs worth of modules may not be quite so happy with 145 megs of modules, so the "make modules_install" never succeeds. This patch allows such users to request modules_install to strip the modules as they are installed. Signed-off-by: "Theodore Ts'o" <> Signed-off-by: Sam Ravnborg <>
