Subject: xfsprogs: useless code blocks
Date: Mon, 20 Jul 2015 09:57:46 -0400 (EDT)	[thread overview]
Message-ID: <1213913978.543970.1437400666553.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <2035333009.511763.1437398166766.JavaMail.zimbra@redhat.com>

Hi all,

I found these useless bits of code in xfsprogs:

repair/incore_ino.c:575-576: 
if (ino_rec->ino_startnum == 0)
  ino_rec = ino_rec;

This one is pretty clear. It is there since 2001 (commit 2bd0ea187 
by nathans@sgi.com, who didn't wrote here since 2006, so I find 
CC-ing him useless). It looks like a forgotten code which doesn't 
do anything, but I ask in case it is a hidden bug.

And:

db/check.c:3035, 3037: Always true expression, as be32_to_cpu() 
translates to __u32 type and unsigned can't be less than zero.

be32_to_cpu(free->hdr.nvalid) < 0 ||

Is there any reason for these tests? I get different type sizes, or
endians as platform dependent, but signed/unsigned? Or it is
a big/little endian conversion hack?

Cheers,
Jan
