Our assumption so far was that if a buffer is given to SCSI HBA driver, then nobody can touch the buffer until the HBA says that he is done with the buffer. It seems that this assumption isn't true. Can you give an instance where somebody (probably buffer cache) will modify the buffer which is handed over to an HBA driver? Thanks, Naveen.
