Author: hselasky Date: Fri Aug 26 12:06:43 2016 New Revision: 304846 URL: https://svnweb.freebsd.org/changeset/base/304846 Log: MFC r304342: Add support for setting blocking and non-blocking mode on /dev/rdma_cm by returning success on FIONBIO and FIOASYNC IOCTLs. The actual flags handling is done by the kern_ioctl() function.
