From: Namhyung Kim <namhyung@...il.com>
To: Jan Kara <jack@...e.cz>, Andrew Morton <akpm@...ux-foundation.org>,
Andreas Dilger <adilger.kernel@...ger.ca>
Cc: linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH] ext3: Coding style fix in namei.c
* break long lines (using temp variables if needed)
* merge short lines
* put open brace on the same line
* use C89-style comments
* remove a space between function name and parenthesis
* remove a space between '*' and pointer name
* add a space after ','
* other random whitespace fixes
