Hmm... ObPatchInQuestion: I'm sorely tempted to shift the big lock in
sys_msync(). It's definitely shiftable to msync_interval(), but there's
more to that - the only non-NULL ->sync in the tree (filemap_sync()) seems
to be almost SMP-safe, possible exception being swap_free().
a) am I right wrt the rest of filemap_sync()?
b) does swap_free() actually need the big lock? Even if it does,
shifting the lock down there will be a big win (we'll need to protect
->fsync() too, indeed, but that still clears the path).
