In that case, maybe it would be simpler to drop it for GFS2. Unless we
are getting a lot of benefit from it, then we should probably just follow
the generic pattern here. Eventually we'll move everything to iomap, so
that the bh mapping interface will be gone. That implies that we might be
able to drop it now, to avoid this complication during the conversion.
Andreas, do you see any issues with that?
I suspect it actually is doing the wrong thing today. It certainly
does for SSDs, and it probably doesn't do a useful thing for modern
disks with intelligent caches either.
Yes, agreed that it makes no sense for SSDs,
Steve.
