![]() This patch adds early checks to avoid burning CPU cycles on the assembly of trace entries which would be skipped anyway. Introduce a static const variable to keep the trace level to check with debug_level_enabled() in sync with the actual trace emit with debug_event(). In order not to refactor the SAN tracing too much, simply use a define instead. This change is only for the non / semi hot paths, while the actual (I/O) hot path was already improved earlier: zfcp_dbf_scsi() is already guarded by its only caller _zfcp_dbf_scsi() since commit |
