Rather than a lock and variable, use a refcount_t to keep track of the number of sub channels. Don't need to wait for subchannels on device removal since wait was already done in device_add. Also fix the error handling; don't wait forever in case of an error on request to create sub channels. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: David S.

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.
