Hi,

ALSA sequencer core has two types of clients; application and kernel.
For kernel clients, the core should handle data in kernel space, meanwhile
this is achieved with a hack of change of address limit. This should be
purged.

This patchset is a revised version of my previous one:
[alsa-devel] obsolete change of address limit
http://mailman.alsa-project.org/pipermail/alsa-devel/2016-August/110937.html

Changes in v2:
 - Use '_IOC_SIZE' macro to calculate the size of argument of ioctl command.
 - Keep redundant longer name.
 - Improve comments.
 - Merge some patches relevant to the same features.

Changes in v3:
 - Improve series of patch
 - Use 'dir' field of ioctl command to detect the length of argument

Regards

  ALSA: seq: add documentation for snd_seq_kernel_client_ctl
  ALSA: seq: add an alternative way to handle ioctl requests
  ALSA: seq: change ioctl command operation to get data in kernel space
