Subject: [PATCH 2/2] iov_iter: fix memory leak in pipe_get_pages_alloc()
Date: Wed,  2 May 2018 20:16:57 +0200	[thread overview]
Message-ID: <1525285017-18616-2-git-send-email-idryomov@gmail.com> (raw)
In-Reply-To: <1525285017-18616-1-git-send-email-idryomov@gmail.com>

Make n signed to avoid leaking the pages array if __pipe_get_pages()
fails.
