Hello,
With kernel 3.14.5...
$ sudo umount /mnt/net/alpha/11
umount: /mnt/net/alpha/11: not mounted
$ sudo mount -o inode_cache,space_cache,compress=lzo,noatime,nossd,skip_balance /dev/nbd11 /mnt/net/alpha/11
$ sudo mount | grep nbd11
/dev/nbd11 on /mnt/net/alpha/11 type btrfs (rw,noatime,compress=lzo,ssd,space_cache,inode_cache,skip_balance)
$ dmesg | tail
...

I'm certain the "nossd" option used to work (prevent the SSD mode) with this
exact same configuration on older kernels. Any idea why it doesn't now?

With respect,
