Subject: [Qemu-devel] [PATCH] linux-user: don't zero a buffer twice
Date: Fri, 02 Oct 2009 14:10:04 +0200 [thread overview]
Message-ID: <1254485404.1738.14.camel@localhost.localdomain> (raw)
prepare_binprm() zeroes bprm->buf. That buffer is already zeroed in
main() and hasn't been touched since so that is not necessary.
Signed-off-by: Paul Bolle <pebolle@tiscali.nl>

Just a minor issue that I noticed while reading the code for some other reason.
bsd-user/bsdload.c could need a similar patch. I haven't looked at that yet.
