Samba4 poor mans debug_ctx()
DEBUG(), DEBUGADD() and friends can now use debug_ctx() in the formatting expressions again, e.g. DEBUG(5,("Guid failed to match: %s\n", GUID_string(debug_ctx(), r->guid))); Sadly it's done with macros (again) but when we need to save the 8 or 16 bytes of object code per DEBUG() expression we can do it the Samba 3 way with added thread-safety for Samba 4. That could save up to 200K, allowing 12 bytes for each occurrance of DEBUG... Signed-off-by: Amin Azez <azez@ufomechanic.net> (This used to be commit 9781967542b00c279563d435aec72dac1e8c7e9a)
