New Revision: 323978
URL: https://svnweb.freebsd.org/changeset/base/323978

Log:
  Change a panic to an error return.
  
  There was a panic() in the NFS server's write operation that didn't
  need to be a panic() and could just be an error return.
  This patch makes that change.
  Found by code inspection during development of the pNFS service.
  
  MFC after:	2 weeks
