New Revision: 286323
URL: https://svnweb.freebsd.org/changeset/base/286323

Log:
  Make fcntl(F_SETFL) work.
  
  The stat_put() system call can be used to modify file descriptor
  attributes, such as flags, but also Capsicum permission bits. Support
  for changing Capsicum bits will be added as soon as its dependent
  changes have been pushed through code review.
