ALSA: rawmidi: Use kvmalloc() for buffers The size of in-kernel rawmidi buffers may be big up to 1MB, and it can be specified freely by user-space; which implies that user-space may trigger kmalloc() errors frequently. This patch replaces the buffer allocation via kvmalloc() for dealing with bigger buffers gracefully. Signed-off-by: Takashi Iwai <tiwai@suse.de>
