New Revision: 222048
URL: http://svn.freebsd.org/changeset/base/222048
Log:
MFC: r221462
Add a comment noting that the NFS code assumes that the
values of error numbers in sys/errno.h will be the same
as the ones specified by the NFS RFCs and that the code
needs to be fixed if error numbers are changed in sys/errno.h.
