[PATCH] export of SEQNUM to userspace (creates /sys/kernel)
o /sys/kernel/hotplug_seqnum exports the current number
o lib/kobject.c's sequence_num is renamed to hotplug_seqnum and
exported by include/linux/kobject.h
o the source file ksysfs.c in kernel/ creates on init the
sybsystem "/sys/kernel/" in sysfs
