A small patchset to update the verbs API documentation with some information regarding the ioctl syscall. First patch converts the file format to ReST, since this is the new preferred format, moves the file to Documentation/userspace-api, and updates the index. The 2nd patch adds the new content, documenting a bit of the internal workings of the kernel side of the API functions. The goal is to make it easier for developers unfamiliar with the structure to understand what is going on when adding a new function.
