changes from v2: only claim one user flag, dont really need more fix patchset grooming err Reported-by: kbuild test robot <lkp@intel.com> quoting tweaks in Docs (unvalidated as better, but likely) rename to lib/dyndbg.c, update docs accordingly
changes from v1: dont drop trim_prefix yet, its harmless, and better supports old compilers. dont move externs to header, despite checkpatch
v1: https://lkml.org/lkml/2019/10/29/989 v2: https://lkml.org/lkml/2019/11/27/547
New Features (review):
accept new query input: file inode.c:100-200 # & line-range file inode.c:start_* # & function
add 'u' user flag, allowing user to compose an arbitrary set of callsites by marking them with 'u', without altering current print-modifying flags.
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 (u+p).
add negating flags to filter on absence of flags, or to negate a modification.
