/*
 * Several of the nfsd.proc4.* entry probes use '.call'.  Why?  On

 * functions.  Besides having different arguments, because those
 * functions are inline systemtap has trouble finding their arguments
 * (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
 * '.call'. which means the function must be a "real" (non-inline)
 * function.
