Subject: [PATCH] fix 'and' typo's
Date: Fri, 26 Oct 2007 21:51:26 +0200 [thread overview]
Message-ID: <4722453E.2090801@tiscali.nl> (raw)
A few patches with changes to net code. I have sent these to the lkml
previously, but they were not yet merged. I am fairly new to kernel
programming, so it is possible that I make some mistakes. I'll explain my
rationale, please nack if incorrect, an additional bit of explanation is
appreciated even more.
The condition '!x & y,' does make little sense: the '!' has a higher
priority than '&'. It behaves therefore like '!x && y'. In the case
bitanding flags, however, '!(x & y)' appears to be desired.
Warning: the change of '!x & y,' to '!(x & y)' may change behavior. if
not desired, I propose changing this to '!x && y', to make it explicitly
clear.
These '&' typo's can be spotted with:
a="A-Za-z0-9_"
git-grep "\![^$a()]*[$a]\+\([$a.]*\|->\)*\(\[[$a.]*\]\)\?[ \W]*&[^&]\+"
--
Fix priority mistakes similar to '!x & y'
