  1. Update eio_ttc.c 

    Lately, we found the substantial delay of cache mode change from writeback to others when write operations are heavy.

The delay is caused by flushing dirty ssd blocks to hard disk, but there is no need to flush.
 I think the dirty blocks on ssd does not affect to the writethrough and readonly mode. The cache consistency can be kept.
