The 'no_sleep_enabled' should be decreased in error handling path
in dm_bufio_client_create() when the DM_BUFIO_CLIENT_NO_SLEEP flag
is set, otherwise static_branch_unlikely() will always return true
even if no dm_bufio_client instances have DM_BUFIO_CLIENT_NO_SLEEP
flag set.

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.
