globalの確認用にLinuxカーネルソース取得

~$ wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.4.6.tar.xz
~$ tar xJf linux-4.4.6.tar.xz
~$

タグ打ち

~$ cd linux-4.4.6
~/linux-4.4.6$ gtags
~/linux-4.4.6$

タグの定義ソースを探す

~/linux-4.4.6$ global start_kernel
arch/alpha/boot/bootp.c
arch/alpha/boot/bootpz.c
arch/alpha/boot/main.c
init/main.c
~/linux-4.4.6$
