Hi :)

I just tried upgrading a server of mine from mainline kernel 3.15.4 to
3.16, and upon reboot no bcache device in sight. Grepping dmesg for
bcache yielded an empty output, and besides the dmesg was full of
oopses.

This is a live server, so I immediately remove kernel 3.16, and upon
reboot, bcache was back and happy.

I know this isn't very useful for anything debugging, but as a very
general question, I'm just wondering if there's something I should
have done prior to upgrading, or if this might be a bug of some sort?

Cheers,
Daniel

Hi Daniel,

Can you post the oops output here? There were no bcache changes from
3.15 to 3.16 so I'm not sure what could have gone wrong.

Good enough for me. I don't have a time window to do debugging on this
server, and I'm looking forward to having a go at the fixes scheduled
for 3.17, so I'm just gonna assume bitrot for this one ;)
