__vmalloc_area_node() allocates pages to cover the requested vmalloc size. This can be a lot of memory. If the current task is killed by the OOM killer, and thus has an unlimited access to memory reserves, it can consume all the memory theoretically. Fix this by checking for fatal_signal_pending and back off early.

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.
