Subject: init/Kconfig: add CONFIG_CC_CAN_LINK
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1a927fd347ebb3c02046150ee489d4fe4e6b9e81;p=linux.git

init/Kconfig: add CONFIG_CC_CAN_LINK

Currently, scripts/cc-can-link.sh is run just for BPFILTER_UMH, but
defining CC_CAN_LINK will be useful in other places.
