+ * depending on where the error occured.
+ *
+ * if the error happens in the waitqueue code because we either timed
+ * out or a signal was raised while waiting, we need to cancel the
+ * userspace i/o operation and free the op manually. this is done to
+ * avoid having the device start writing application data to our shared
+ * bufmap pages without us expecting it.
+ *
+ * FIXME: POSSIBLE OPTIMIZATION:
+ * However, if we timed out or if we got a signal AND our upcall was never
+ * picked off the queue (i.e. we were in OP_VFS_STATE_WAITING), then we don't
+ * need to send a cancellation upcall. The way we can handle this is
+ * set error_exit to 2 in such cases and 1 whenever cancellation has to be
+ * sent and have handle_error
+ * take care of this situation as well..
+ *
+ * if a pvfs2 sysint level error occured and i/o has been completed,
+ * there is no need to cancel the operation, as the user has finished
+ * using the bufmap page and so there is no danger in this case. in
+ * this case, we wake up the device normally so that it may free the
+ * op, as normal.
+ *
+ * note the only reason this is a macro is because both read and write
+ * cases need the exact same handling code.
