44 * When adding tracepoints and debug messages we have various choices.
45 * Some considerations:
47 * Use cifs_dbg(VFS, ...) for things we always want logged, and the user to see
48 * cifs_info(...) slightly less important, admin can filter via loglevel > 6
49 * cifs_dbg(FYI, ...) minor debugging messages, off by default
50 * trace_smb3_* ftrace functions are preferred for complex debug messages
51 * intended for developers or experienced admins, off by default
