fs/9p: add 9P2000.L renameat operation
renameat - change name of file or directory size[4] Trenameat tag[2] olddirfid[4] oldname[s] newdirfid[4] newname[s] size[4] Rrenameat tag[2] older Trename have the below request format size[4] Trename tag[2] fid[4] newdirfid[4] name[s] The rename message is used to change the name of a file, possibly moving it to a new directory. The rename opreation is actually a directory opertation and should ideally have olddirfid, if not we cannot represent the fid on server with anything other than name. We will have to derive the old directory name from fid in the Trename request. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
