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).
