Zeng Jingxiang bd6e21a904 fs/reiserfs/inode: remove dead code in _get_block_create_0() 
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]

README 

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.
