Use a single no_mem_stripes list instead of per member device lists for handling stripes that need retrying in case of failed io_unit allocation. Because io_units are allocated from a memory pool shared between all member disks, the no_mem_stripes list should be checked when an io_unit for any member is freed. This fixes a deadlock that could happen if there are stripes in more than one no_mem_stripes list.

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.
