-Subject: [PATCH] net/packet: move reference count in packet_sock to 64 bits
-
-In some potential instances the reference count on struct packet_sock
-could be saturated and cause overflows which gets the kernel a bit
-confused.  To prevent this, move to a 64bit atomic reference count to
-prevent the possibility of this type of overflow.
-
-Because we can not handle saturation, using refcount_t is not possible
-in this place.  Maybe someday in the future if it changes could it be
-used.
-
-Original version from Daniel after I did it wrong, I've provided a
-changelog.
