In the past we had problems when an rsb had a reference counter greater than one while in the toss state. An rsb in the toss state is not actively used for locking, and should not have any other references apart from the single ref keeping it on the rsb hash. Shift to freeing rsb's directly rather than using kref_put to free them, since the ref counting is not meant to be used in this state. Add warnings if ref counting is seen while an rsb is in the toss state. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.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 reStructuredText 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.
