commit104f268d43upstream. This is really being used as an assert that the expected usecnt is being held and implicitly that the usecnt is valid. Rename it to assert_uverbs_usecnt and tighten the checks to only accept valid values of usecnt (eg 0 and < -1 are invalid). The tigher checkes make the assertion cover more cases and is more likely to find bugs via syzkaller/etc. Fixes:3832125624("IB/core: Add support for idr types") Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
