Subject: [PATCH] change compat shmget size arg to signed
Date: Mon, 20 Feb 2006 19:39:36 +0100	[thread overview]
Message-ID: <20060220183936.GA31091@suse.de> (raw)


change second arg (the 'size') to signed to handle a size of -1.
ltp test shmget02 fails. This patch fixes it.
Oddly, we see the failure only on a POWER4 LPAR with 4.6G ram.
