Subject: [Qemu-devel] [PATCH 4/6] file_ram_alloc: change length argument to size_t (v2)
Date: Mon,  2 Jul 2012 15:06:36 -0300	[thread overview]
Message-ID: <1341252398-12268-5-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1341252398-12268-1-git-send-email-ehabkost@redhat.com>

While we are at it, rename it to "length", as "memory" doesn't mean
anything.

Changes v1 -> v2:
 - Rebase after coding style changes
