Subject: [PATCH 33/40] staging/lustre/target: move OUT to the unified target code
From: Mikhail Pershin <mike.pershin@...el.com>
- Move OUT handler to the unified target code, so it can be
used by both MDS and OST.
- Make OFD able to handle OUT requests.
- Rename MDS_MDS_PORTAL to the OUT_PORTAL and MDS_OUT_... defines
just OUT_... since they are independent from MDS now.
