* (PR 1155). Finally, those functions are just simple wrappers
* around their nfsd_* counterparts (for example, nfsd4_lookup() is a
* wrapper for nfsd_lookup). As a comment in fs/nfsd/nfs4proc.c says:
*
* Note: some routines in this file are just trivial wrappers
* (e.g. nfsd4_lookup()) defined solely for the sake of consistent
* naming.
*
* So, we'll just ignore those inline wrappers by specifying
