Kees Cook 86cb30ec07 treewide: setup_timer() -> timer_setup() (2 field) ... This converts all remaining setup_timer() calls that use a nested field to reach a struct timer_list. Coccinelle does not have an easy way to match multiple fields, so a new script is needed to change the matches of "&_E->_timer" into "&_E->_field1._timer" in all the rules. spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup-2fields.cocci @fix_address_of depends@ expression e;
