From: J. Bruce Fields <[EMAIL PROTECTED]>
We've been using the convention that vfs_foo is the function that calls
a filesystem-specific foo method if it exists, or falls back on a
generic method if it doesn't.
So rename setlease to vfs_setlease, and __setlease to setlease. Keep
setlease exported to allow filesystems to use the generic method in
addition to doing their own bookkeeping.
