I have monitored udev when modprobing dlm module and those are the udev
events being triggered:

(k)rafaeldtinoco at clubionic01:~$ sudo udevadm monitor --kernel
monitor will print the received events for:
KERNEL - the kernel uevent

KERNEL[10516.364250] add      /module/dlm (module)
KERNEL[10516.364425] add      /kernel/slab/:0000496 (slab)
KERNEL[10516.364579] add      /kernel/slab/:0000312 (slab)
KERNEL[10516.364730] add      /devices/virtual/misc/dlm-control (misc)
KERNEL[10516.364849] add      /devices/virtual/misc/dlm-monitor (misc)
KERNEL[10516.364980] add      /devices/virtual/misc/dlm_plock (misc)

and when being removed:

KERNEL[10713.488367] remove   /devices/virtual/misc/dlm_plock (misc)
KERNEL[10713.488465] remove   /devices/virtual/misc/dlm-control (misc)
KERNEL[10713.488539] remove   /devices/virtual/misc/dlm-monitor (misc)
KERNEL[10713.488635] remove   /kernel/slab/:0000496 (slab)
KERNEL[10713.488692] remove   /kernel/slab/:0000312 (slab)
KERNEL[10713.488825] remove   /module/dlm (module)
