Subject: [PATCH] sym53c8xx_2: free luntbl in sym_hcb_free
Date: Mon, 21 Jul 2008 15:58:32 -0700 [thread overview]
Message-ID: <20080721225832.GA4516@linux.vnet.ibm.com> (raw)
From: Mike Anderson <andmike@linux.vnet.ibm.com>
This patch frees the luntbl dma area in sym_hcb_free if allocated.
Since the luntbl is part of a larger dma coherent area not freeing the
luntbl kept a 64k dma coherent area previous allocated through
dma_alloc_coherent allocated. This prevented a DLPAR remove IO
operation from completing successfully.
