[PATCH 00/16] dynamic-debug cleanups, 2 new features

[Jim Cromie]

random cleanups of obsolete code, comments, verbose output, etc.

accept new query input:
  file inode.c:100-200
  file inode.c:start_*

add 'xyz' user flags to callsites' flagstate, allowing user to compose
a set of callsites by marking them with user flags.

extend flags-spec to allow filter-flags, which select callsites for
modification based upon their current flagstate.  This lets user
activate the set of callsites composed previously.

Jim Cromie (16):
  dyndbg: drop trim_prefix, obsoleted by __FILE__s relative path
  dyndbg: drop overwrought comment on ddebug_proc_open
  dyndbg: raise verbosity needed to enable ddebug_proc_* logging
  dyndbg: rename __verbose section to __dyndbg
  dyndbg: parse flags last, restore original behavior
  dyndbg: fix overcounting of ram used by dyndbg
  dyndbg: fix a BUG_ON in ddebug_change
  dyndbg: refactor parse_linerange out of ddebug_parse_query
  dyndbg: accept 'file foo.c:func1' and 'file foo.c:10-100'
  dyndbg: refactor ddebug_read_flags out of ddebug_parse_flags
  dyndbg: combine flags & mask into a struct, use that
  dyndbg: add filter parameter to ddebug_parse_flags
  dyndbg: extend ddebug_parse_flags to accept optional filter-flags
  dyndbg: prefer declarative init in caller, to memset in callee
  dyndbg: add inverted-flags, implement filtering on flags
  dyndbg: allow inverted-flag-chars in modflags

[PATCH 00/16] dynamic-debug cleanups, 2 new features

[Jim Cromie]

this is v2 of patchset posted earlier:
https://lkml.org/lkml/2019/10/29/989

changes from v1:
  dont drop trim_prefix yet, its harmless, and better supports old compilers.
  dont move externs to header, despite checkpatch

New Features (review):

accept new query input:
  file inode.c:100-200
  file inode.c:start_*

add 'xyz' user flags, allowing user to compose an arbitrary set of
callsites by marking them with user flags.  This takes 3 remaining
bits in the flags byte.

extend flags-spec to allow filter-flags, which select callsites for
modification based upon their current flags.  This lets user activate
the set of callsites composed previously (xy+p).
