Hello Martin,

Today if a BLKDISCARD ioctl passes a non-aligned start and/or end sector to the kernel then the block layer will submit invalid (non-aligned) REQ_DISCARD requests to the block driver the ioctl applies to. This is not acceptable. Does the above mean that you are proposing to fail such BLKDISCARD ioctls with an error code?

Thanks,

Bart.
