GFS2: Issue discards in 512b sectors This patch changes GFS2's discard issuing code so that it calls function sb_issue_discard rather than blkdev_issue_discard. The code was calling blkdev_issue_discard and specifying the correct sector offset and sector size, but blkdev_issue_discard expects these values to be in terms of 512 byte sectors, even if the native sector size for the device is different. Calling sb_issue_discard with the BLOCK size instead ensures the correct block-to-512b-sector translation. I verified that "minlen" is specified in blocks, so comparing it to a number of blocks is correct.
