VNPL 1.1 is slightly reworded to make it clear that proprietary software
interacting with Vitastor and providing some kind of service to end users isn't
a "Proxy Program" if it's not specially designed to be used with Vitastor.
For example, Windows OS running in a virtual machine stored in a Vitastor
cluster clearly isn't.
This makes sense for some SSDs like Intel D3-4510 because they don't
like overwrites of the same sector:
$ fio -direct=1 -rw=write -bs=4k -size=4k -loops=100000 -iodepth=1
write: IOPS=3142, BW=12.3MiB/s (12.9MB/s)(97.9MiB/7977msec)
$ fio -direct=1 -rw=write -bs=4k -size=128k -loops=100000 -iodepth=1
write: IOPS=20.8k, BW=81.4MiB/s (85.3MB/s)(543MiB/6675msec)
- Do not block flock() requests
- Fix stop_client(0) attempts leading to std::bad_function_call
- Fix degraded writes crashing due to an unset stripes[i].missing (at least with a missing parity device)
- Fix recovery B/W reporting
