[Qemu-devel] [PATCH] linux-user: don't zero a buffer twice

[Qemu-devel] [PATCH] linux-user: don't zero a buffer twice

[Paul Bolle]

prepare_binprm() zeroes bprm->buf. That buffer is already zeroed in
main() and hasn't been touched since so that is not necessary.

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.
