Subject: FRV: possibly bad unsigned comparison in show_backtrace()
Date: Mon, 08 Feb 2010 17:08:05 +0100 [thread overview]
Message-ID: <4B7036E5.7050601@gmail.com> (raw)
In arch/frv/kernel/traps.c, show_backtrace(), if sp is 0
then the dump does not succeed because stop was set to 0
and unaltered when we reach the unsigned comparison:
while (tos < stop) {...}
The naming stop may on the other hand suggest that this
is desired, is it?
