dynamic_debug: reuse generic string_unescape function

2013-05-01T00:04:03+00:00

There is kernel function to do the job in generic way. Let's use it.

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...

device and dynamic_debug: Use dev_vprintk_emit and dev_printk_emit

2012-09-17T13:10:05+00:00

Convert direct calls of vprintk_emit and printk_emit to the
dev_ equivalents.

Make create_syslog_header static.

netdev_printk/netif_printk: Remove a superfluous logging colon

2012-09-17T13:10:05+00:00

netdev_printk originally called dev_printk with %pV.

This style emitted the complete dev_printk header with
a colon followed by the netdev_name prefix followed
by a colon.

Now that netdev_printk does not call dev_printk, the
extra colon is superfluous.  Remove it.

Example:
old: sky2 0000:02:00.0: eth0: Link is up at 100 Mbps, full duplex, flow control both
new: sky2 0000:02:00.0 eth0: Link is up at 100 Mbps, full duplex, flow control both

netdev_printk/dynamic_netdev_dbg: Directly call printk_emit

2012-09-17T13:08:30+00:00

A lot of stack is used in recursive printks with %pV.

Using multiple levels of %pV (a logging function with %pV
that calls another logging function with %pV) can consume
more stack than necessary.

Avoid excessive stack use by not calling dev_printk from
netdev_printk and dynamic_netdev_dbg.  Duplicate the logic
and form of dev_printk instead.

Make __netdev_printk static.
Remove EXPORT_SYMBOL(__netdev_printk)
Whitespace and brace style neatening.

dev_dbg/dynamic_debug: Update to use printk_emit, optimize stack

2012-09-17T13:08:30+00:00

commit c4e00daaa9
("driver-core: extend dev_printk() to pass structured data")
changed __dev_printk and broke dynamic-debug's ability to control the
dynamic prefix of dev_dbg(dev,..).

commit af7f2158fd
("drivers-core: make structured logging play nice with dynamic-debug")
made a minimal correction.

The current dynamic debug code uses up to 3 recursion levels via %pV.
This can consume quite a bit of stack.  Directly call printk_emit to
reduce the recursion depth.

These changes include:

dev_dbg:
o Create and use function create_syslog_header to format the syslog
  header for printk_emit uses.
o Call create_syslog_header and neaten __dev_printk
o Make __dev_printk static not global
o Remove include header declaration of __dev_printk
o Remove now unused EXPORT_SYMBOL() of __dev_printk
o Whitespace neatening

dynamic_dev_dbg:
o Remove KERN_DEBUG from dynamic_emit_prefix
o Call create_syslog_header and printk_emit
o Whitespace neatening

Revert "dynamic_debug: remove unneeded includes"

2012-05-07T23:47:32+00:00

This reverts commit 04db6e5fddca55186b6a74339a62c800150648bc.

Odds are, we really don't want to revert all of these, and need to be
more careful in the future to make sure we don't break the build of
other arches.
