*	ALSA: timer: Limit max instances per timer	Takashi Iwai	2017-11-06	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Currently we allow unlimited number of timer instances, and it may bring the system hogging way too much CPU when too many timer instances are opened and processed concurrently. This may end up with a soft-lockup report as triggered by syzkaller, especially when hrtimer backend is deployed. Since such insane number of instances aren't demanded by the normal use case of ALSA sequencer and it merely opens a risk only for abuse, this patch introduces the upper limit for the number of instances per timer backend. As default, it's set to 1000, but for the fine-grained timer like hrtimer, it's set to 100.

*	ALSA: timer: Introduce disconnect op to snd_timer_instance	Takashi Iwai	2016-01-21	1	-0/+1
\| \| \| \| \| \| \| \| \|	Instead of the previous ugly hack, introduce a new op, disconnect, to snd_timer_instance object for handling the wake up of pending tasks more cleanly. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=109431 Signed-off-by: Takashi Iwai <tiwai@suse.de>

*	[ALSA] Unregister device files at disconnection	Takashi Iwai	2006-09-23	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \|	Orignally proposed by Sam Revitch <sam.revitch@gmail.com>. Unregister device files at disconnection to avoid the futher accesses. Also, the dev_unregister callback is removed and replaced with the combination of disconnect + free. A new function snd_card_free_when_closed() is introduced, which is used in USB disconnect callback. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

*	[ALSA] timers: add module refcounting for global timers	Clemens Ladisch	2005-11-04	1	-0/+1
\| \| \| \| \| \| \| \| \| \|	Modules: RTC timer driver,Timer Midlevel Add a module pointer to the timer structure and use it for refcounting instead of the card's module pointer to prevent the global timer modules (rtctimer and hpetimer) from being removed while in use.

	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
