Randy Dunlap c2554b4764 TOMOYO: fix __setup handlers return values ... [ Upstream commit 39844b7e30 ] __setup() handlers should return 1 if the parameter is handled. Returning 0 causes the entire string to be added to init's environment strings (limited to 32 strings), unnecessarily polluting it. Using the documented strings "TOMOYO_loader=string1" and "TOMOYO_trigger=string2" causes an Unknown parameter message: Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc5 TOMOYO_loader=string1 \ TOMOYO_trigger=string2", will be passed to user space. and these strings are added to init's environment string space: Run /sbin/init as init process with arguments: /sbin/init with environment: HOME=/ TERM=linux BOOT_IMAGE=/boot/bzImage-517rc5 TOMOYO_loader=string1 TOMOYO_trigger=string2 With this change, these __setup handlers act as expected, and init's environment is not polluted with these strings.
