Author: emaste

New revision: 324683
URL: https://svnweb.freebsd.org/changeset/base/324683

Log:
  write.2: correct maximum nbytes size for EINVAL error

  In FreeBSD 11 and later debug.iosize_max_clamp defaults to 0, and the
  maximum nbytes count for write(2) is SSIZE_MAX. Update the man page to
  document this, and mention the sysctl that can be set to obtain the
  previous behaviour.
