+/*
+ * This module implements parseable logging for all Samba VFS operations.
+ *
+ * You use it as follows:
+ *
+ * [tmp]
+ * path = /tmp
+ * vfs objects = full_audit
+ * full_audit:prefix = %u|%I
+ * full_audit:success = open opendir create_file
+ * full_audit:failure = all
+ *
+ * vfs op can be "all" which means log all operations.
+ * vfs op can be "none" which means no logging.
+ *
+ * This leads to syslog entries of the form:
+ * smbd_audit: nobody|192.168.234.1|opendir|ok|/tmp
+ * smbd_audit: nobody|192.168.234.1|create_file|fail (No such file or directory)|0x1|file|open|/ts/doesNotExist
+ * smbd_audit: nobody|192.168.234.1|open|ok|w|/tmp/file.txt
+ * smbd_audit: nobody|192.168.234.1|create_file|ok|0x3|file|open|/tmp/file.txt
+ *
+ * where "nobody" is the connected username and "192.168.234.1" is the
+ * client's IP address.
+ *
+ * Options:
+ *
+ * prefix: A macro expansion template prepended to the syslog entry.
+ *
+ * success: A list of VFS operations for which a successful completion should
+ * be logged. Defaults to no logging at all. The special operation "all" logs
+ * - you guessed it - everything.
+ *
+ * failure: A list of VFS operations for which failure to complete should be
+ * logged. Defaults to logging everything.
