ISTR asking this before, but I cannot find an answer in the previous
threads just now.

Do things like the 0xd0 event really need all the UEVENT things spelled
out? And 0x22d0 (LOCK_STORES) still appears missing going by the pattern
in there.

Also, it looks like the 0xc5 things want to be UEVENT, the current EVENT
thing will mask the umask.
