+/*
+ * How the locks work together
+ *
+ * There are two locks: spinlock dirty_lock protecting the dirty
+ * rectangle, and mutex mm_lock protecting mappings.
+ *
+ * The problem is that dirty rectangle and mappings aren't
+ * independent: the dirty rectangle must cover all faulted pages in
+ * mappings. We need to prove that our locking maintains this
+ * invariant.
+ *
+ * There are several kinds of critical regions:
+ *
+ * 1. Holding only dirty_lock: xenfb_refresh(). May run in
+ * interrupts. Extends the dirty rectangle. Trivially preserves
+ * invariant.
+ *
+ * 2. Holding only mm_lock: xenfb_mmap() and xenfb_vm_close(). Touch
+ * only mappings. The former creates unfaulted pages. Preserves
+ * invariant. The latter removes pages. Preserves invariant.
+ *
+ * 3. Holding both locks: xenfb_vm_nopage(). Extends the dirty
+ * rectangle and updates mappings consistently. Preserves
+ * invariant.
+ *
+ * 4. The ugliest one: xenfb_update_screen(). Clear the dirty
+ * rectangle and update mappings consistently.
+ *
+ * We can't simply hold both locks, because zap_page_range() cannot
+ * be called with a spinlock held.
+ *
+ * Therefore, we first clear the dirty rectangle with both locks
+ * held. Then we unlock dirty_lock and update the mappings.
+ * Critical regions that hold only dirty_lock may interfere with
+ * that. This can only be region 1: xenfb_refresh(). But that
+ * just extends the dirty rectangle, which can't harm the
+ * invariant.
+ *
+ * But FIXME: the invariant is too weak. It misses that the fault
+ * record in mappings must be consistent with the mapping of pages in
+ * the associated address space! do_no_page() updates the PTE after
+ * xenfb_vm_nopage() returns, i.e. outside the critical region. This
+ * allows the following race:
+ *
+ * X writes to some address in the Xen frame buffer
+ * Fault - call do_no_page()
+ * call xenfb_vm_nopage()
+ * grab mm_lock
+ * map->faults++;
+ * release mm_lock
+ * return back to do_no_page()
+ * (preempted, or SMP)
+ * Xen worker thread runs.
+ * grab mm_lock
+ * look at mappings
+ * find this mapping, zaps its pages (but page not in pte yet)
+ * clear map->faults
+ * releases mm_lock
+ * (back to X process)
+ * put page in X's pte
+ *
+ * Oh well, we wont be updating the writes to this page anytime soon.
