I'm lazy, so I choose to fix the document rather than changing every dev_dbg() call. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

Dynamic Debug: Introduce ddebug_query= boot parameter 2010-10-22T17:16:42+00:00 Thomas Renninger trenn@suse.de 2010-08-06T14:11:02+00:00 a648ec05bb950fae2f35d0490ddd6cf15010af72 Dynamic debug lacks the ability to enable debug messages at boot time. One could patch initramfs or service startup scripts to write to /sys/../dynamic_debug/control, but this sucks. This patch makes it possible to pass a query in the same format one can write to /sys/../dynamic_debug/control via boot param. When dynamic debug gets initialized, this query will automatically be applied.

Dynamic debug: allow simple quoting of words 2009-03-24T23:38:27+00:00 Greg Banks gnb@melbourne.sgi.com 2009-02-06T01:54:26+00:00 9898abb3d23311fa227a7f46bf4e40fd2954057f Allow simple quoting of words in the dynamic debug control language. This allows more natural specification when using the control language to match against printk formats, e.g #echo -n 'format "Setting node for non-present cpu" +p' > /mnt/debugfs/dynamic_debug/control instead of #echo -n 'format Setting\040node\040for\040non-present\040cpu +p' > /mnt/debugfs/dynamic_debug/control Adjust the dynamic debug documention to describe that and provide a new example. Adjust the existing examples in the documentation to reflect the current whitespace escaping behaviour when reading the control file. Fix some minor documentation trailing whitespace.

Allow simple quoting of words in the dynamic debug control language.

This allows more natural specification when using the control language
to match against printk formats, e.g

#echo -n 'format "Setting node for non-present cpu" +p' >
	/mnt/debugfs/dynamic_debug/control

instead of

#echo -n 'format Setting\040node\040for\040non-present\040cpu +p' >
	/mnt/debugfs/dynamic_debug/control

Adjust the dynamic debug documention to describe that and provide a
new example.  Adjust the existing examples in the documentation to
reflect the current whitespace escaping behaviour when reading the
control file.  Fix some minor documentation trailing whitespace.
