commit fea013e020e6ecc7be75bea0d61697b7e916b44d upstream.
Feature bits have to be encoded into the correct locations. This hasn't
been an issue so far because the only hole in the feature bits was in bit
10 (CEPHFS_FEATURE_RECLAIM_CLIENT), which is located in the 2nd byte. When
adding more bits that go beyond the this 2nd byte, the bug will show up.
[xiubli: remove incorrect comment for CEPHFS_FEATURES_CLIENT_SUPPORTED]
Fixes: 9ba1e224538a ("ceph: allocate the correct amount of extra bytes for the session features")

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.
