svn commit: r260409 - releng/10.0/sys/kern

[Mateusz Guzik]

Author: mjg

New Revision: 260409
URL: http://svnweb.freebsd.org/changeset/base/260409

Log:
  MFC r260232:
  Don't check for fd limits in fdgrowtable_exp.
  
  Callers do that already and additional check races with process
  decreasing limits and can result in not growing the table at all, which
  is currently not handled.
