commit 4cd1103d8c66b2cdb7e64385c274edb0ac5e8887 upstream. Patch series "ocfs2: fix a deadlock case". This fixes a deadlock case in ocfs2. We firstly export jbd2 symbols jbd2_journal_[grab|put]_journal_head as preparation and later use them in ocfs2 insread of jbd_[lock|unlock]_bh_journal_head to fix the deadlock. This patch (of 2): This exports symbols jbd2_journal_[grab|put]_journal_head, which will be used outside modules, e.g. ocfs2.

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.
