[LU-3033] Remove dependency for lu_env structure in lu_cdebug_printer

Sun, 16 Jan 2022 07:46:10 +0000

I was investigating the possibility of removing the need for an lu_env structure from ll_releasepage (as a result of ~~LU-2622~~), and the first hurdle seems to be the fact that the debug infrastructure relies on this. In particular, it seems lu_cdebug_printer uses this structure to provide a temporary buffer so consecutive, non-newline terminated, calls to the print functions can be concatenated into a single message.

Thus, unless the debug log infrastructure is reworked, I wont be able to remove the lu_env dependency. Since anything modifying the debug log code is likely to touch a lot of lines, I wanted to get some opinions on whether restructuring this would be advantageous.

Is the debug logging infrastructure something that can/should be reworked to be more straight forward and simpler?
