By enabling the new option "More verbose debugging", information about source file and line number will be added to debugging message. This is sample output, EDAC MC0: Giving out device to 'e7xxx_edac' 'E7205': DEV 0000:00:00.0 EDAC DEBUG: in drivers/edac/edac_pci.c, line at 48: edac_pci_alloc_ctl_info() EDAC DEBUG: in drivers/edac/edac_pci.c, line at 334: edac_pci_add_device() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Signed-off-by: Hitoshi Mitake <h.mitake@gmail.com> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
