Subject[PATCH] ext3: Coding style fix in namei.c
Date
 * 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
