Subject: Re: [PATCH] zram: set zram bio priority to REQ_PRIO.

People really need to stop randomly using REQ_PRIO.  It was added
back then because I did not want to overload REQ_META for WBT
priorisation, but it looks other added this somewhat bogus
priorisation back anyway.  If that is to stay it should probably
just go away entirely, but certainly not added for magic boosters
for normal data I/O.
