Commit Message

Alan Adamson Feb. 21, 2024, 6:36 p.m. UTC 
Tests the ability to enable and disable error logging for passthru admin commands issued to
the controller and passthru IO commands issued to a namespace.

These tests will only be run on kernels that export the passthru_err_log_enabled
attribute.
