Since commit 27b3a5c51b ("kill-the-bkl/reiserfs: drop the fs race
watchdog from _get_block_create_0()"), which removed a label that may
have the pointer 'p' touched in its control flow, related if statements
now eval to constant value now. Just remove them.
Assigning value NULL to p here
293 char *p = NULL;
In the following conditional expression, the value of p is always NULL,
As a result, the kunmap() cannot be executed.
308 if (p)
309 kunmap(bh_result->b_page);
355 if (p)
356 kunmap(bh_result->b_page);
366 if (p)
367 kunmap(bh_result->b_page);
Also, the kmap() cannot be executed.
399 if (!p)
400 p = (char *)kmap(bh_result->b_page);
[JK: Removed unnecessary initialization of 'p' to NULL]

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.
