[ Upstream commit 135e724547 ]
Provide precision hints to snprintf() since we know the destination
buffer size of the RX/TX ring names are IFNAMSIZ + 5 - 1. This fixes the
following warnings:
drivers/net/ethernet/intel/e1000e/netdev.c: In function
'e1000_request_msix':
drivers/net/ethernet/intel/e1000e/netdev.c:2109:13: warning: 'snprintf'
output may be truncated before the last format character
[-Wformat-truncation=]
"%s-rx-0", netdev->name);
^

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.
