sc_data_direction and bidi commands

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. -- To

[PATCH] block: create ioctl to discard-or-zeroout a range of blocks

Create a new ioctl to expose the block layer's newfound ability to issue either a zeroing discard, a WRITE SAME with a zero page, or a regular write with the zero page. This BLKZEROOUT2 ioctl takes {start, length, flags} as parameters. So far, the only flag available is to enable the zeroing
