hurd/ChangeLog
2014-08-21  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>.
