Linux kernel source tree
b353756b2b
If kmemleak built in to the kernel, but is disabled by default, the debugfs file is never registered. Because of this, it is not possible to find out if the kernel is built with kmemleak support by checking for the presence of this file. To allow this, always register the file. After this patch, if the file doesn't exist, kmemleak is not available in the kernel. If writing "scan" or any other value than "clear" to this file results in EBUSY, then kmemleak is available but is disabled by default and can be activated via the kernel command line. Catalin: "that's also consistent with a late disabling of kmemleak when the debugfs entry sticks around."

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
