currently, for verbose=3, these are logged (blank lines for clarity): dyndbg: query 0: "class DRM_UT_CORE +p" mod:* dyndbg: split into words: "class" "DRM_UT_CORE" "+p" dyndbg: op='+' dyndbg: flags=0x1 dyndbg: *flagsp=0x1 *maskp=0xffffffff dyndbg: parsed: func="" file="" module="" format="" lineno=0-0 class=... dyndbg: no matches for query dyndbg: no-match: func="" file="" module="" format="" lineno=0-0 class=... dyndbg: processed 1 queries, with 0 matches, 0 errs That is excessive, so this patch: - shrinks 3 lines of 2nd stanza to single line - drops 1st 2 lines of 3rd stanza 3rd is like 1st, with result, not procedure. 2nd is just status, retold in 4th, with more info.
