[Gluster-devel] question about nfs lookup result

Hi all, I'm reading the code of 3.6.9 version and got a question.And I'm
not very familiar with the code,so I have to confirm it(I checked the
master branch,it's same with 3.6.9).
The question is about the 'lookup' operation of NFS.And i'm with this code
nfs3_lookup (nfs3.c) ==> nfs3_fh_resolve_and_resume ==>
nfs3_fh_resolve_root ==> nfs3_fh_resolve_resume ==> nfs3_fh_resolve_entry
Now enter the "nfs_entry_loc_fill" and return with -1 which means the
"parent" not found,so we have to do hard resolve about the parent. After
doing a hard resolve,we get into the callback
"nfs3_fh_resolve_inode_lookup_cbk".And the callback has the following code:
>>> memcpy (&cs->stbuf, buf, sizeof(*buf)); >>> memcpy (&cs->postparent,
I think we've just done a parent resolve,how could we assign the parent
result into the "stbuf" and "postparent".The later two should be the
information of the child file/directory.Do i made a misunderstand?
Thanks advance for your help.
