dynamic debug: line queries failing due to uninitialized local variable

2013-08-28T19:10:53Z

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. Signed-off-by: Jason Baron Signed-off-by: Greg Kroah-Hartman

dynamic_debug: reuse generic string_unescape function

2013-05-01T00:04:03Z

There is kernel function to do the job in generic way. Let's use it. Signed-off-by: Andy Shevchenko Cc: Jason Baron Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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

2013-04-30T01:28:19Z

There are at least two users of isodigit(). Let's make it a public function of ctype.h. Signed-off-by: Andy Shevchenko Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

dynamic_debug: add pr_errs before -EINVALs

2013-01-17T20:19:09Z

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

2013-01-17T20:18:07Z

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... Signed-off-by: Joe Perches Signed-off-by: Jason Baron Signed-off-by: Greg Kroah-Hartman

lib: dynamic_debug: use kbasename()

2012-12-18T01:15:17Z

Remove the custom implementation of the functionality similar to kbasename(). Signed-off-by: Andy Shevchenko Cc: Jason Baron Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

device and dynamic_debug: Use dev_vprintk_emit and dev_printk_emit

2012-09-17T13:10:05Z

Convert direct calls of vprintk_emit and printk_emit to the dev_ equivalents. Make create_syslog_header static. Signed-off-by: Joe Perches Acked-by: David S. Miller Tested-by: Jim Cromie Acked-by: Jason Baron Signed-off-by: Greg Kroah-Hartman

netdev_printk/netif_printk: Remove a superfluous logging colon

2012-09-17T13:10:05Z

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 Signed-off-by: Joe Perches Acked-by: David S.

netdev_printk/dynamic_netdev_dbg: Directly call printk_emit

2012-09-17T13:08:30Z

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. Signed-off-by: Joe Perches Acked-by: David S.

dev_dbg/dynamic_debug: Update to use printk_emit, optimize stack

2012-09-17T13:08:30Z

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 Signed-off-by: Joe Perches Acked-by: David S.
