Subject: [PATCH] [SCSI] aacraid: Use kcalloc instead of kzalloc to allocate array
Date: Tue, 29 Nov 2011 22:08:00 +0100 [thread overview]
Message-ID: <1322600880.1534.328.camel@localhost.localdomain> (raw)
The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.
The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107
