Description

after running "zfstest" and then using "reboot -d" and "::findleaks", there's a couple of leaks like the following:

kmem_alloc_8 leak: 2 buffers, 8 bytes each, 16 bytes total
ADDR BUFADDR TIMESTAMP THREAD
CACHE LASTLOG CONTENTS
ffffff071a067978 ffffff071a0416c0 9b097add290 ffffff002126fc40

luaV_execute+0x355
luaD_call+0x88
f_call+0x1d
luaD_rawrunprotected+0x69
luaD_pcall+0x55

I've attached a copy of the output of "::findleaks -df" to this bug, which contains these leaks.
