Subject[PATCH v2 07/20] dyndbg: reduce verbose/debug clutter
Date
currently, for verbose=3, this is logged:

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=DRM_UT_CORE
dyndbg: no matches for query
dyndbg: no-match: func="" file="" module="" format="" lineno=0-0 class=DRM_UT_CORE
dyndbg: processed 1 queries, with 0 matches, 0 errs

This patch:

shrinks 3 lines of 2nd stanza to single line

drops 2 middle lines of 3rd stanza
3 differs from 1 only by status
2 is just status, retold in 4, with more info.
