Hey Ian,

I had a question for Jan, but in reply to the previous version of the
patch so you might have missed it:

https://lore.kernel.org/all/alpine.DEB.2.22.394.2111050825240.284830@ubuntu-linux-20-04-desktop/


However, the concern is about resource utilization and slowness, rather
than correctness, so I think the version of the patch you committed
should work OK (unless it turns out that with broken EFI firmware
opening HandleProtocol/OpenVolume and closing it many times causes
some sort of error.) So maybe for 4.16 we are OK as is and we can make
any changes (if necessary) for 4.17.
