When an interface is part of a namespace it is possible that ixgbevf_close() may be called while ixgbevf_suspend() is running which ends up in a double free WARN and/or a BUG in free_msi_irqs() To handle this situation we extend the rtnl_lock() to protect the call to netif_device_detach() and check for !netif_device_present() to avoid entering close while in suspend. Also added rtnl locks to ixgbevf_queue_reset_subtask().

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.
