    Subject[PATCH 4.19 276/287] cifs: return errors during session setup during reconnects
    Date
    From: Shyam Prasad N <sprasad@microsoft.com>

    commit 8ea21823aa584b55ba4b861307093b78054b0c1b upstream.

    During reconnects, we check the return value from
    cifs_negotiate_protocol, and have handlers for both success
    and failures. But if that passes, and cifs_setup_session
    returns any errors other than -EACCES, we do not handle
    that. This fix adds a handler for that, so that we don't
    go ahead and try a tree_connect on a failed session.
