When the client sends a regular blocking accept request, the backend is expected to return only when the accept is completed, simulating a blocking behavior, or return an error. Specifically, on EAGAIN from inet_accept, the backend shouldn't return "EAGAIN" to the client. Instead, it should simply continue the wait. Otherwise, the client will send another accept request, which will cause another EAGAIN to be sent back, which is a waste of resources and not conforming to the expected behavior. Change the behavior by turning the "goto error" into a return.

README
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.
