There is a mixture of mutex and spinlocks to protect receive context (rcd/uctxt) information. This is not used consistently. Use the mutex to protect device receive context information only. Use the spinlock to protect sub context information only. Protect access to items in the rcd array with a spinlock and reference count. Remove spinlock around dd->rcd array cleanup. Since interrupts are disabled and cleaned up before this point, this lock is not useful.

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.
