Hi, I filed a bug about the io read_bytes count issue. https://bugzilla.kernel.org/show_bug.cgi?id=202211 Check the document linux/Documentation/filesystems/proc.txt about read_bytes description. I'm not sure if it suits cifs. Please close this bug if you think it's not a bug. Documenttaion: read_bytes ---------- I/O counter: bytes read Attempt to count the number of bytes which this process really did cause to be fetched from the storage layer. Done at the submit_bio() level, so it is accurate for block-backed filesystems. <please add status regarding NFS and CIFS at a later time> -- Best regards!
