kmemleak does one slab allocation per user allocation. So if slab fault injection is enabled to any degree, kmemleak instantly fails to allocate and turns itself off. However, it's useful to use kmemleak with fault injection to find leaks on error paths. On the other hand, checking kmemleak itself is not so useful because (1) it's a debugging tool and (2) it has a very regular allocation pattern (basically a single allocation site, so it either works or not). Turn off fault injection for kmemleak allocations.

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.
