commit ee5814dddefbaa181cb247a75676dd5103775db1 upstream. Since the fsverity sysctl registration runs as a builtin initcall, there is no corresponding sysctl deregistration and the resulting struct ctl_table_header is not used. This can cause a kmemleak warning just after the system boots up. (A pointer to the ctl_table_header is stored in the fsverity_sysctl_header static variable, which kmemleak should detect; however, the compiler can optimize out that variable.) Avoid the kmemleak warning by using register_sysctl_init() which is intended for use by builtin initcalls and uses kmemleak_not_leak().

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.
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.
