Unfortunately commit81200b0265("selinux: checkreqprot is deprecated, add some ssleep() discomfort") added a five second sleep during early kernel boot, e.g. start_kernel(), which could cause a "scheduling while atomic" panic. This patch fixes this problem by moving the sleep out of checkreqprot_set() and into sel_write_checkreqprot() so that we only sleep when the checkreqprot setting is set during runtime, after the kernel has booted. The error message remains the same in both cases. Fixes:81200b0265("selinux: checkreqprot is deprecated, add some ssleep() discomfort") Reported-by: J.

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.
