[PATCH] Interface to invalidate regions of mmaps
From: "Paul E. McKenney" <paulmck@us.ibm.com>
The patch reworks and generalises vmtruncate_list() a bit to create an API
which invalidates a specified portion of an address_space, permitting
distributed filesystems to maintain POSIX semantics when a file mmap()ed on
one client is modified on another client.
