dyndbg: test DECLARE_DYNDBG_CLASSMAP, sysfs nodes
Demonstrate use of DECLARE_DYNDBG_CLASSMAP macro, and expose them as
sysfs-nodes for testing.
For each of the 4 class-map-types:
- declare a class-map of that type,
- declare the enum corresponding to those class-names
- share _base across 0..30 range
- add a __pr_debug_cls() call for each class-name
- declare 2 sysnodes for each class-map
for 'p' flag, and future 'T' flag
These declarations create the following sysfs parameter interface:
:#> pwd
/sys/module/test_dynamic_debug/parameters
:#> ls
T_disjoint_bits T_disjoint_names T_level_names T_level_num do_prints
p_disjoint_bits p_disjoint_names p_level_names p_level_num
NOTES:
The local wrapper macro is an api candidate, but there are already too
many parameters. OTOH, maybe related enum should be in there too,
since it has _base inter-dependencies.
The T_* params control the (future) T flag on the same class'd
pr_debug callsites as their p* counterparts. Using them will fail,
until the dyndbg-trace patches are added in.
