Fsck should be fixed now

There is no new commit, I'm at

    bcache: fix device hot add

Ok, you're good then (at least re: the buffered reads bug)

I suspect that problem is due to using --metadata_replicas=2. If you have a
some spare time please try fileystsem formated with this parameters:
# bcache format --compression_type=gzip --metadata_replicas=2
--data_checksum_type=crc64 --metadata_checksum_type=crc64 --tier=2 /dev/sde1
--tier=3 /dev/sdd1

Alright, will do

I configured logging using netconsole, I formated fs using favorite killer-combo[1], when I copied ~480000 rather small files the host rebooted. I only cought this:
