This flag is modified during run time, possibly even when the RTNL lock is not held. Additionally it has a few places which should be using test_and_set or test_and_clear atomic bit operations. Create a new state bit __I40E_UDP_SYNC_PENDING and use it instead of the ole I40E_FLAG_UDP_FILTER_SYNC flag. This is part of a larger effort to remove the need for using cmpxchg64 in i40e_set_priv_flags.

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.
