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
Changes in v4:
- Update kernel API documentation
- Use logical AND to detect ioctl direction
Takashi Sakamoto (4): 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 ALSA: seq: obsolete change of address limit
JFYI, as I'm on vacation (also in the next week), I'll apply later once when back to work.
thanks,
Takashi
