commit 392a17b10ec4320d3c0e96e2a23ebaad1123b989 upstream. When I set the timeout to a specific value such as 500ms, the timeout event will not happen in time due to the overflow in function check_msg_timeout: ... ent->timeout -= timeout_period; if (ent->timeout > 0) return; ... The type of timeout_period is long, but ent->timeout is unsigned long. This patch makes the type consistent.

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.
