(netfs_S_file_record_lock): Add new argument mach_port_t rendezvous. 2016-05-23 Svante Signell * netfs.h (struct peropen): Change the type of rlock_status from an int to a struct rlock_peropen. (struct node): Change the type of userbox from a struct lock_box to a struct rlock_box. * dir-lookup.c (netfs_S_dir_lookup): Use fshelp_rlock_tweak. * file-lock-stat.c (netfs_S_file_lock_stat): Total rewrite around the new record locking functions. * file-lock.c (netfs_S_file_lock): Likewise. * file-record-lock.c (netfs_S_file_record_lock): Likewise. * make-node.c (netfs_make_node): Initialize userbox with fshelp_rlock_init. * make-peropen.c (netfs_make_peropen): Initialize lock_status using fshelp_rlock_po_init. (netfs_make_peropen): Add a comment that po->refcnt starts at zero. * relese-peropen.c (netfs_release_peropen): Release lock_status using fshelp_rlock_drop_peropen. 2001-04-11 Neal H Walfield * file-record-lock.c: New file. Implement netfs_S_file_record_lock. * Makefile (SRCS): Add file-record-lock.c --- libnetfs/netfs.h | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) (limited to 'libnetfs/netfs.h') diff --git a/libnetfs/netfs.h b/libnetfs/netfs.h index 625aa963..d6a13bb1 100644 --- a/libnetfs/netfs.h +++ b/libnetfs/netfs.h @@ -1,6 +1,6 @@ /* - - Copyright (C) 1994,95,96,97,99,2000,02,13 Free Software Foundation, Inc. + Copyright (C) 1994-1997, 1999, 2000, 2002, 2013-2019 + Free Software Foundation, Inc.
