dynamic_debug: fix ddebug_parse_query()

2014-01-28T05:02:39+00:00

This fixes following scenario:

  $ echo 'file dynamic_debug.c line 1-123 +p' > /sys/kernel/debug/dynamic_debug/control
  -bash: echo: write error: Invalid argument
  $ dmesg | grep dynamic_debug
  dynamic_debug:ddebug_parse_query: last-line:123 < 1st-line:1
  dynamic_debug:ddebug_parse_query: query parse failed

dynamic_debug: remove wrong error message

2014-01-28T05:02:39+00:00

parse_lineno() returns either negative error code or zero.  We don't
need to print something here because if parse_lineno fails it will print
error message.

dynamic_debug: add wildcard support to filter files/functions/modules

2014-01-24T00:36:55+00:00

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" > /dynamic_debug/control
2.  open debug logs for usb xhci code
    echo "file *xhci* +p" > /dynamic_debug/control

dynamic debug: line queries failing due to uninitialized local variable

2013-08-28T19:10:53+00:00

Settings of the form, 'line x module y +p', can fail arbitrarily due to an
uninitialized local variable. With this patch results are consistent, as
expected.

lib, net: make isodigit() public and use it

2013-04-30T01:28:19+00:00

There are at least two users of isodigit().  Let's make it a public
function of ctype.h.

dynamic_debug: add pr_errs before -EINVALs

2013-01-17T20:19:09+00:00

Ma noted that dynamic-debug is silent about many query errors, so add
pr_err()s to explain those errors, and tweak a few others.  Also parse
flags 1st, so that match-spec errs are slightly clearer.

dynamic_debug: Fix vpr_ logging styles

2013-01-17T20:18:07+00:00

vpr_info_dq should be a function and vpr_info should have
a do {} while (0)

Add missing newlines to pr_s.

Miscellaneous neatening too.
braces, coalescing formats, alignments, etc...
