Chuck Lever 6019ce0742 NFSD: Add a tracepoint to record directory entry encoding 
Enable watching the progress of directory encoding to capture the
timing of any issues with reading or encoding a directory. The
new tracepoint captures dirent encoding for all NFS versions.

For example, here's what a few NFSv4 directory entries might look
like:

nfsd-989   [002]   468.596265: nfsd_dirent:          fh_hash=0x5d162594 ino=2 name=.
nfsd-989   [002]   468.596267: nfsd_dirent:          fh_hash=0x5d162594 ino=1 name=..
nfsd-989   [002]   468.596299: nfsd_dirent:          fh_hash=0x5d162594 ino=3827 name=zlib.c
nfsd-989   [002]   468.596325: nfsd_dirent:          fh_hash=0x5d162594 ino=3811 name=xdiff
nfsd-989   [002]   468.596351: nfsd_dirent:          fh_hash=0x5d162594 ino=3810 name=xdiff-interface.h
nfsd-989   [002]   468.596377: nfsd_dirent:          fh_hash=0x5d162594 ino=3809 name=xdiff-interface.c
