Samba has a module vfs_full_audit, what does each object actually mean within the module?

The module vfs_full_audit in Samba lists objects that can be added to the module to increase the logging specificity or verbosity generally of syscalls. Example: # defaults for auditing full_audit:priority = notice full_audit:facility = local6 full_audit:failure = create_file open opendir rmdir unlink unlinkat connect connectpath disconnect full_audit:success = rename opendir rmdir unlink open create_file opendir unlinkat connect connectpath disconnect full_audit:prefix = %U|%d|%u|%R|%I|%S However in the man page located here: https://www.samba.org/samba/docs/current/man-html/vfs_full_audit.8.html It fails to define explicitly what each object actually does - I understand that some of them are fairly obvious such as "open" or "rmdir" but a sentence just describing what each part does would be very useful for more questionable ones such as "kernel_flock" Does anyone know of any resource/URL that defines these values explicitly? Or perhaps this has been asked previously by one of you and had data back from Sernet detailing it? Thanks for looking ;)
