Hi Luis, These 4 patches alter pr_debug() messages for more info, and less log-spam. * add "for $modname:" to banners helpful for finding one of many [ 40.885922] main:layout_sections: Core section allocation order for test_dynamic_debug: ~20 lines of output [ 40.885967] main:move_module: Final section addresses for test_dynamic_debug: ~2 lines - .init.text/data * add symbol name to "Absolute symbol: <value>" val ~== 0 - less interesting than name [ 40.886006] main:simplify_symbols: Absolute symbol: 0x00000000 test_dynamic_debug.c [ 40.886008] main:simplify_symbols: Absolute symbol: 0x00000000 test_dynamic_debug.mod.c * add size to section report. gives more info.
