Moya * diskfs.h (struct node): Add filemod_reqs member. (struct modreq): Rename struct dirmod to reqmod as it is used for directory and file notifications. (diskfs_notice_filechange): Add prototype. * dir-chg.c (diskfs_S_dir_notice_changes): Check nowait_dir_changed return value for errors. (diskfs_notice_dirchange): Remove requests when the notification fails. * file-chg.c (diskfs_S_file_notice_changes): Implement. (diskfs_notice_filechange): New function. * node-make.c (diskfs_make_node): Initialize filemod_reqs. * node-drop.c (free_modreqs): New function. (diskfs_drop_node): Free filemod_reqs. * file-chauthor.c (dithkfth_TH_file_chauthor): Add file notifications. * file-chflags.c (diskfs_S_file_chflags): Likewise. * file-chmod.c (diskfs_S_file_chmod): Likewise. * file-chown.c (diskfs_S_file_chown): Likewise. * file-set-size.c (diskfs_S_file_set_size): Likewise. * io-prenotify.c (diskfs_S_io_prenotify): Likewise. * io-write.c (diskfs_S_io_write): Likewise. * node-rdwr.c (diskfs_node_rdwr): Likewise. --- libdiskfs/diskfs.h | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) (limited to 'libdiskfs/diskfs.h') diff --git a/libdiskfs/diskfs.h b/libdiskfs/diskfs.h index c0bf5a06..33717f80 100644 --- a/libdiskfs/diskfs.h +++ b/libdiskfs/diskfs.h @@ -100,7 +100,9 @@ struct node struct conch conch; - struct dirmod *dirmod_reqs; + struct modreq *dirmod_reqs; + + struct modreq *filemod_reqs; off_t allocsize; @@ -118,11 +120,11 @@ enum lookup_type RENAME, }; -/* Pending directory modification request */ -struct dirmod +/* Pending directory and file modification request */ +struct modreq { mach_port_t port; - struct dirmod *next; + struct modreq *next; }; @@ -748,6 +750,14 @@ void diskfs_notice_dirchange (struct node *dp, enum dir_changed_type type, char *name); +/* Send notifications to users who have requested them with + file_notice_changes for file NP.
