A fault due to a version mismatch or a feature set mismatch used to be treated differently from other faults: the connection would get closed without trying to reconnect and there was a ->bad_proto() connection op for notifying about that. This changed a long time ago, see commits6384bb8b8e("libceph: kill bad_proto ceph connection op") and0fa6ebc600("libceph: fix protocol feature mismatch failure path"). Nowadays these aren't any different from other faults (i.e. we try to reconnect even though the mismatch won't resolve until the server is replaced). reset_connection() calls there are rather confusing because reset_connection() resets a session together an individual instance of the protocol. This is cleaned up in the next patch. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
