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). cc: Jim Cromie (16): dyndbg-docs: eschew file /full/path query in docs dyndbg: drop obsolete comment on ddebug_proc_open dyndbg: raise verbosity needed to enable ddebug_proc_* logging dyndbg: rename __verbose section to __dyndbg dyndbg: fix overcounting of ram used by dyndbg dyndbg: fix a BUG_ON in ddebug_describe_flags 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 dyndbg: make ddebug_tables list LIFO for add/remove_module .../admin-guide/dynamic-debug-howto.rst | 72 +++-- include/asm-generic/vmlinux.lds.h | 6 +- include/linux/dynamic_debug.h | 7 +- kernel/module.c | 2 +- lib/dynamic_debug.c | 283 +++++++++++------- 5 files changed, 232 insertions(+), 138 deletions(-) -- 2.23.0
