  call trace.
- [PATCHv2 5/5] fix a mistake.

Changed for V2:
- [PATCHv2 1/5] just fixes some small spelling and other mistakes.
  And as the initial patch, here sets cmd area to 8M and data area to
  1G(1M fixed and 1023M growing)
- [PATCHv2 2/5] is a new one, adding global data block pool support.
  The max total size of the pool is 2G and all the targets will get
  growing blocks from here.
  Test this using multi-targets at the same time.
- [PATCHv2 3/5] changed nothing, respin it to avoid the conflict.
- [PATCHv2 4/5] and [PATCHv2 5/5] are new ones.
