Subject: [Kernel-janitors] [PATCH] change kmalloc() auditing in aha1542.c
Date: Wed, 21 Jan 2004 03:32:14 +0000 [thread overview]
Message-ID: <20040121033214.GA1414@masterofpi.org> (raw)
Hi,
The aha1542 driver calls panic() if kmalloc() fails, which it shouldn't
do. This patch changes that by having the code return a nonzero value, so
it tells the SCSI mid-layer to retry the command, as suggested by Randy.
