2019-02-01  Svante Signell <svante.signell@gmail.com>

	* Update copyright years.

2018-01-05  Svante Signell <svante.signell@gmail.com>

	* Update copyright years.
        * fs.defs: Add new argument rendezvous: mach_port_send_t to RPC
        file_record_lock.

2017-01-05  Svante Signell <svante.signell@gmail.com>

	* Update copyright years and headers.

2016-05-23  Svante Signell <svante.signell@gmail.com>

	* fs.defs: Added description.
	* hurd_types.defs: Make struct flock_t seven integers long since
	  l_start and l_len are 64bit.
	* hurd_types.h: typedef flock_t as flock64.

2001-04-10  Neal H Walfield  <neal@cs.uml.edu>

	* fs.defs: New RPC file_record_lock.
	* hurd_types.defs: Import <fcntl.h>.
