Description Kim Scarborough 2022-02-15 09:05:20 UTC 
I have "nomultichannel" specified in my CIFS fstab line, but the kernel still spams my console with "multichannel is not supported on this protocol version, use 3.0 or above". Can it just be assumed that I don't care if multichannel isn't supported if I've specifically turned it off, and have this message be suppressed?

Thanks for pointing this out. Have patch in for-next, and will get this into 5.17 soon (and cc:stable for 5.16)
