52 | * When adding tracepoints and debug messages we have various choices. | |
53 | * Some considerations: | |
54 | * | |
55 | * Use cifs_dbg(VFS, ...) for things we always want logged, and the user to see | |
56 | * cifs_info(...) slightly less important, admin can filter via loglevel > 6 | |
57 | * cifs_dbg(FYI, ...) minor debugging messages, off by default | |
58 | * trace_smb3_* ftrace functions are preferred for complex debug messages | |
59 | * intended for developers or experienced admins, off by default | |
