Currently there is one cmd timeout timer and one qfull timer for each udev, and whenever any new command is coming in we will update the cmd timer or qfull timer. For some corner cases the timers are always working only for the ringbuffer's and full queue's newest cmd. That's to say the timer won't be fired even if one cmd has been stuck for a very long time and the deadline is reached. This fix will keep the cmd/qfull timers to be pended for the oldest cmd in ringbuffer and full queue, and will update them with the next cmd's deadline only when the old cmd's deadline is reached or removed from the ringbuffer and full queue.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
