There were individual waitqueues for each epfile but eps_enable would iterate through all of them, resulting in essentially the same wakeup time. The waitqueue represents the function being enabled, so a central waitqueue in ffs_data makes more sense and is less redundant. Also use wake_up_interruptible to reflect use of wait_event_interruptible.

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.
