It adds a few query parsing conveniences; accept combined file:line & file:func forms file inode.c:100-200 # file & line-range file inode.c:start_* # file & function Then it expands flags: Adds 'u' user flag, allowing user to compose an arbitrary set of callsites by marking them with 'u', without altering current print-modifying flags. Adds 'PFMLTU' flags, which negate their lower-case counterparts. Extends flags-spec with filter-flags, which select callsites for modification based upon their current flags. This lets user activate the set of callsites marked with 'u' in a batch. echo 'u+p' > control This was previously submitted before events overtook. v1: https://lkml.org/lkml/2019/10/29/989 v2: https://lkml.org/lkml/2019/11/27/547 Jim Cromie (16): cleanups: dyndbg-docs: eschew file /full/path query in docs dyndbg: drop obsolete comment on ddebug_proc_open dyndbg: refine debug verbosity dyndbg: rename __verbose section to __dyndbg dyndbg: fix overcounting of ram used by dyndbg dyndbg: fix a BUG_ON in ddebug_describe_flags dyndbg: make ddebug_tables list LIFO for add/remove_module new features: -parsing conveniences dyndbg: refactor parse_linerange out of ddebug_parse_query dyndbg: accept 'file foo.c:func1' and 'file foo.c:10-100' -flags extensions --internal rework 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 --expose the features dyndbg: add user-flag, negating-flags, and filtering on flags dyndbg: allow negating flag-chars in modflags .../admin-guide/dynamic-debug-howto.rst | 75 +++-- include/asm-generic/vmlinux.lds.h | 6 +- include/linux/dynamic_debug.h | 5 +- kernel/module.c | 2 +- lib/dynamic_debug.c | 282 ++++++++++-------- 5 files changed, 225 insertions(+), 145 deletions(-) -- 2.26.2
