We need to prevent resubmission of the context immediately following an initial resubmit (which does a lite-restore preemption). Currently we do this by disabling all submission whilst the context is still active, but we can improve this by limiting the restriction to only until we receive notification from the context-switch interrupt that the lite-restore preemption is complete.

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.
