- * Reordering precautions: make sure that request processing that
- * was able to receive its bulk data should not get reordered with
- * overlapping BRW requests, e.g.
- * 1) BRW1 sent, bulk data received, but disk I/O delayed
- * 2) BRW1 resent and fully processed
- * 3) the page was unlocked on the client and its writeback bit reset
- * 4) BRW2 sent and fully processed
- * 5) BRW1 processing wakes up and writes stale data to disk
- * If on step 1 bulk data was not received, client resend will invalidate
- * its bulk descriptor and the RPC will be dropped due to failed bulk
- * transfer, which is just fine.
