From: "Du, Changbin" <[email protected]>
These patches are to make it easier to filter kernel debug logs which
we want.
Whith wildcard support, below command can enable all usb debug logs:
#echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control
This patch only enables two wildcard:
'*' - matches zero or more characters
'?' - matches one character
Changes since v4:
moved matching function to lib/parser.c
Du, Changbin (3):
lib/parser.c: add match_wildcard function
dynamic_debug: add wildcard support to filter files/functions/modules
dynamic-debug-howto.txt: update since new wildcard support
