Yes please.

Mike, Mikulas,

Could you please review patch 4 ? It is a long standing issue with DM but now
that zone write plugging fakes a smaller 128 max open zones limit for drives
with no limits, zonefs gets confused and tests fail. So it would be great to
get this patch in for 6.10 as a fix.
Thanks !
