dynamic_debug: add wildcard support to filter files/functions/modules
Add wildcard '*'(matches zero or more characters) and '?' (matches one character) support when qurying debug flags. Now we can open debug messages using keywords. eg: 1. open debug logs in all usb drivers echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control 2. open debug logs for usb xhci code echo "file *xhci* +p" > <debugfs>/dynamic_debug/control Signed-off-by: Du, Changbin <changbin.du@gmail.com> Cc: Jason Baron <jbaron@akamai.com> Cc: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
