New Revision: 194106
URL: http://svn.freebsd.org/changeset/base/194106

Log:
  Remove the static from int hardlink_check_uid.
  There is an external use in the opensolaris code.
  
  I am not sure how this ever worked but I have seen two reports of:
  	link_elf: symbol hardlink_check_uid undefined
  lately.
