The wait-queue head parameters and variables are named in a couple of ways, we have the following variants currently: wait_queue_head_t *q wait_queue_head_t *wq wait_queue_head_t *head In particular the 'wq' naming is ambiguous in the sense whether it's a wait-queue head or entry name - as entries were often named 'wait'. ( Not to mention the confusion of any readers coming over from workqueue-land. ) Standardize all this around a single, unambiguous parameter and variable name: struct wait_queue_head *wq_head which is easy to grep for and also rhymes nicely with the wait-queue entry naming: struct wait_queue_entry *wq_entry Also rename: struct __wait_queue_head => struct wait_queue_head ... and use this struct type to migrate from typedefs usage to 'struct' usage, which is more in line with existing kernel practices. Don't touch any external users and preserve the main wait_queue_head_t typedef.

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.
