For CONFIG_PROC_FS=n, the /proc is not mountable, but the /proc directory has been created in the prepare() stage whenever /proc is there or not. so, the checking of /proc in the run_syscall() stage will be always true and at last it will fail all of the procfs dependent test cases, which deviates from the 'cond' check design of the EXPECT_xx macros, without procfs, these test cases should be skipped instead of failed. To solve this issue, one method is checking /proc/self instead of /proc, another method is removing the /proc directory completely for CONFIG_PROC_FS=n, we apply the second method to avoid misleading the users.

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.
