New Revision: 207689
URL: http://svn.freebsd.org/changeset/base/207689
Log:
If the "-alldirs" export option was used for the V4: line, mountd
would crash in check_options() since dp == NULL for the V4: line.
This patch moves the check for options allowed on the V4: line to
ahead of where dp is used to avoid this crash.
