Author: jilles Date: Thu Aug 9 15:11:38 2012 New Revision: 239151 URL: http://svn.freebsd.org/changeset/base/239151 Log: ftw(): Do not check the maxfds argument against OPEN_MAX. Apart from the fact that nothing should have OPEN_MAX as a limit (as opposed to RLIMIT_NOFILE from getrlimit() or _SC_OPEN_MAX from sysconf()), POSIX does not require us to check this. POSIX does have a requirement on the application that maxfds not exceed {OPEN_MAX}, but does not require the implementation to check it ("may fail").
