Per the IBTA spec, QP destroy shall fail if the QP is attached to multicast groups, although the spec is silent on modify_qp to reset state. It implies that ULP must deregister QP from all mcast groups for destroy to succeed. The faulty patch "IB/ipoib: Update broadcast object if PKey value was changed in index 0" exposed two issues in rdmavt: 1. Rvt QP reset waits for qp references to go to zero. This will hang if QP is attached to multicast groups. 2. The mcast group detach will fail for a QP in reset state therefore preventing ULP from correcting the issue. This patch moves the reference count wait to the the destroy QP path and allows a QP mcast detach to work in the reset state.

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.
