2016-01-04T15:26:58+00:00

A _lot_ of ->write() instances were open-coding it; some are
converted to memdup_user_nul(), a lot more remain...

lib/dynamic_debug.c: use kstrdup_const

2015-11-07T01:50:42+00:00

Using kstrdup_const, thus reusing .rodata when possible, saves around 2 kB
of runtime memory on my laptop/.config combination.

module: add extra argument for parse_params() callback

2015-05-20T07:25:24+00:00

This adds an extra argument onto parse_params() to be used
as a way to make the unused callback a bit more useful and
generic by allowing the caller to pass on a data structure
of its choice. An example use case is to allow us to easily
make module parameters for every module which we will do
next.

lib/dynamic_debug.c: use seq_open_private() instead of seq_open()

2014-10-14T00:18:14+00:00

Using seq_open_private() removes boilerplate code from ddebug_proc_open().

The resultant code is shorter and easier to follow.

This patch does not change any functionality.

net: print net_device reg_state in netdev_* unless it's registered

2014-07-21T03:38:43+00:00

This way we'll always know in what status the device is, unless it's
running normally (i.e. NETDEV_REGISTERED).

Also, emit a warning once in case of a bad reg_state.
