Subject: [BUGFIX PATCH v2 3/5] selftests: net: Use size_t and ssize_t for counting file size
Date: Mon, 21 Oct 2019 17:28:27 +0900	[thread overview]
Message-ID: <157164650777.17692.4048211617331943317.stgit@devnote2> (raw)
In-Reply-To: <157164647813.17692.3834082082658965225.stgit@devnote2>

Use size_t and ssize_t correctly for counting send file size
instead of unsigned long and long, because long is 32bit on
32bit arch, which is not enough for counting long file size (>4GB).
