[ Upstream commit8ac1ee6f4d] Clang warns that the address of a pointer will always evaluated as true in a boolean context: drivers/net/ethernet/mellanox/mlx4/eq.c:243:11: warning: address of array 'eq->affinity_mask' will always evaluate to 'true' [-Wpointer-bool-conversion] if (!eq->affinity_mask || cpumask_empty(eq->affinity_mask)) ~~~~~^~~~~~~~~~~~~ 1 warning generated. Use cpumask_available, introduced in commitf7e30f01a9("cpumask: Add helper cpumask_available()"), which does the proper checking and avoids this warning.

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.
