backport 32feee36c30ea06e38ccb8ae6e5c44c6eec790a6 to 4.15.0-176.185

backport 32feee36c30ea06e38ccb8ae6e5c44c6eec790a6 to 4.15.0-176.185

[Nikhil Kshirsagar]

Hello all,

I am trying to backport 32feee36c30ea06e38ccb8ae6e5c44c6eec790a6
(https://www.spinics.net/lists/kernel/msg4386275.html) onto
4.15.0-176.185 , please could someone help me understand which other
patches I need? The cherry-pick needs manual resolution, which I did,
but this is the issue I run into - https://pastebin.com/nBxdpHdJ

I'd be very grateful for some help with this.

Regards,
Nikhil.

Hello all!

As mentioned in the earlier email, I am trying to backport
32feee36c30ea06e38ccb8ae6e5c44c6eec790a6 to kernel 4.15.0-176_185

This is the diff that built the kernel successfully -
https://pastebin.com/Ce41Hqaa , and I had to apply it manually since
the cherry-pick did not apply cleanly and there were many conflicts.
The main issue seems to be that struct cache_set does not contain
multiple cache devices in the upstream code, but in 4.15 it did.

Since I am not aware of the internals of the bcache code, I am not
sure if it might cause unintended side effects, so I would appreciate
any input about this backport, and if it is a correct backport.

Regards,
Nikhil.
