Kernel

the number of different uevent actions that can be emitted by the kernel these days is limited, and seems to be fixed. from include/linux/kobject.h: 40 /* 41 * The actions here must match the index to the string array 42 * in lib/kobject_uevent.c 43 * 44 * Do not add new actions here without checking with the driver-core 45 * maintainers. Action strings are not meant to express subsystem 46 * or device specific properties.
