The original uevent_notify() has two additional mechanisms:
C1. Save events in suspend-again context and show them up at wakeup.
C2. If the new event is a duplicated event, ignore it.

Questions:
Q1. Have you checked if C1 is met with the modification? Besides, have
you made it sure that the modification won't change the behavior of
suspend-again context? (whether "theoretical" or "experimental")
Q2. Do you still support C2?
  For example, if we have notifited the user that we are charging
  30 seconds ago, we should never bother the user with another message
  that declares that it is charging unless we have notified that
  we are not charging since then.

Cheers,
MyungJoo.
