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.
