Author: emaste Date: Tue Oct 24 00:32:20 2017 New Revision: 324942 URL: https://svnweb.freebsd.org/changeset/base/324942 Log: MFC r324683: 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.
