Subject: [PATCH] filemap: define PROC_SUPER_MAGIC, avoid linux/magic.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #1848 caused build issues with some "unusual" build configurations
– apparently we can't rely on linux/magic.h being present when
cross-building for musl libc.

Defining PROC_SUPER_MAGIC should not cause a problems since it should
be considered part of the Linux kernel/user API and it is unlikely to
change.
