libdiskfs: Support for file record locking
2019-03-04 Svante Signell <svante.signell@gmail.com>
* file-lock.c: Make flock work regardless of the
mode in which the file was opened.
2019-02-12 Svante Signell <svante.signell@gmail.com>
* file-lock.c: Comment out "Make flock work without R or W mode"
2019-02-01 Svante Signell <svante.signell@gmail.com>
* Update copyright years.
* file-record-lock.c(diskfs_S_file_record_lock):
Don't set rendezvous to MACH_PORT_NULL.
2018-12-07 Svante Signell <svante.signell@gmail.com>
* Update copyright years.
* dir-lookup.c(diskfs_S_dir_lookup): Call fshelp_rlock_tweak()
with new last argument rendezvous = MACH_PORT_NULL.
* file-lock.c(diskfs_S_file_lock): Likewise.
* file-record-lock.c(diskfs_S_file_record_lock): Likewise.
(diskfs_S_file_record_lock): Add new argument mach_port_t rendezvous.
2017-01-05 Svante Signell <svante.signell@gmail.com>
* Update copyright years and headers.
2016-05-23 Svante Signell <svante.signell@gmail.com>
* file-lock-stat.c: Port from cthreads to libpthread.
* file-lock.c: Likewise.
* file-record-lock: Likewise.
2001-04-11 Neal H Walfield <neal@cs.uml.edu>
* Makefile (FSSRCS): Add file-record-lock.c.
* diskfs.h (struct peropen): Change the type of lock_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 (diskfs_S_dir_lookup): Use fshelp_rlock_tweak
as fshelp_acquire_lock is now depreciated.
* file-lock-stat.c (diskfs_S_file_lock_stat): Total rewrite
around the new record locking functions.
* file-lock.c (diskfs_S_file_lock): Total rewrite around the
new record locking functions.
* file-record-lock.c: New file. Implement
diskfs_S_file_record_lock.
* node-make.c (diskfs_make_node): Initialize userbox with
fshelp_rlock_init.
* peropen-make.c (diskfs_make_peropen): Initialize lock_status
using fshelp_rlock_po_init.
* peropen-rele.c (diskfs_release_peropen): Release lock_status
using fshelp_rlock_drop_peropen.
