Subject: sc_data_direction and bidi commands
Date: Wed, 21 Jan 2015 17:18:43 +0100 [thread overview]
Message-ID: <54BFD163.4020802@sandisk.com> (raw)
Hello,
Although several SCSI LLDs compare sc_data_direction with the value
DMA_BIDIRECTIONAL apparently scsi_setup_cmnd() never sets
sc_data_direction to the value DMA_BIDIRECTIONAL. Is this behavior on
purpose ? I discovered this while debugging bidi support in a SCSI LLD.
Thanks,
Bart.
