[stgt] [PATCH 0/4] Pass-through direct-store blocksize properties

[Andy Grover]

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.

Thanks -- Regards -- Andy
