--- Comment #6 from Mark Johnston <markj@FreeBSD.org> ---
(In reply to Mark Johnston from comment #5)
I spent a bit of time looking at this, but for g_raid it's quite non-trivial
and hard to test.  My patch for gmirror also relaxes synchronization perhap=
s a
bit too much, in that inconsistencies are possible (e.g., disk state
transitions and syncid/genid bumps happen without locking), though it fixes=
 the
larger problem.

My comment about GEOM gate is wrong, the topology lock simply can't be drop=
ped.
 Fortunately, that one is easy to fix.
