Hi Tomo, This patchset is trying to address this issue: https://bugzilla.redhat.com/show_bug.cgi?id=747510 In short, if the LUN is backed by a direct-store device, we want to report the same block characteristics as our backing device does. This set adds support for the Block Limits VPD (0xB0) and fills in some additional fields in READ CAPACITY (16), which are queried by tgt-admin and passed in. I have tested that the new regexes in tgt-admin work, and everything else looks pretty straightforward, but it still needs more testing, preferably by somebody with 4K drives.
