38 | * When adding tracepoints and debug messages we have various choices. | |
39 | * Some considerations: | |
40 | * | |
41 | * Use cifs_dbg(VFS, ...) for things we always want logged, and the user to see | |
42 | * cifs_info(...) slightly less important, admin can filter via loglevel > 6 | |
43 | * cifs_dbg(FYI, ...) minor debugging messages, off by default | |
44 | * trace_smb3_* ftrace functions are preferred for complex debug messages | |
45 | * intended for developers or experienced admins, off by default | |
