[openib-general] ib_post_recv buffer re-use

Application I'm working on needs to receive and process messages
from RQ, so I dma_map and ib_post_recv pool of buffers. 
Then after I receive a message I plan to reuse already mapped
buffer for consequent ib_post_recv. Is that safe? Should I worry
about dma syncronisation?

Thanks,
