Subject: [PATCH] jffs2 whitespace
Date: Thu, 22 Sep 2005 18:05:49 -0600 [thread overview]
Message-ID: <1127433949.6937.30.camel@localhost.localdomain> (raw)
[-- Attachment #1: Type: text/plain, Size: 1072 bytes --]
I'm not sure if anyone else really cares about these kind of cleanup
changes, but just in case someone does, here is a patch that fixes up
several whitespace issues in the jffs2 code.
I believe all of these changes are consistent with what the mtd
developers like to see in the code. There seems to be a lot of precedent
for all of these changes.
There are no functional changes in this patch.
Here are the specific issues addressed:
* Remove all trailing whitespace
* Use tab-indentation consistently (there was some space indentation)
* Consistent placement of parenthesis for "if", "for", "while", and
"switch" expressions (i.e. "if (a == b)" instead of "if( a == b )")
* Space follows all commas
* Space around binary operators (i.e. "a = b + c;" instead of "a=b+c;")
* Opening brace of function definition on its own line
* Put the "else" on the same line as the preceding and following braces
This is a rather large patch, but the changes are trivial. If this patch
goes over well, I would be happy to create a similar patch for the rest
of the mtd code.

[JFFS2] Whitespace cleanup
Remove all trailing whitespace.
Use tab-indentation consistently.
Changed "if( ... )" to "if (...)", same for "for" and "while".
Always have a space after a comma ",..." to ", ...".
Use whitespace around binary operators "x+3" to "x + 3".
No space after function name "int foo (char bar)" to "int foo(char bar)".
Opening brace for function on its own line.
"else" on same line as preceding and following braces.
