Takashi Iwai 0981a260a1 [ALSA] Fix possible invalid memory access in PCM core
snd_internval_list() may access invalid memory in the case count = 0
is given.  It shouldn't be passed, but it'd better to make the code
a bit more robust.

Clemens Ladisch 9a826ddba6 [ALSA] pcm core: fix silence_start calculations
The case where silence_size < boundary was broken because different
parts of the snd_pcm_playback_silence() function disagreed about whether
silence_start should point to the start or to the end of the buffer part
to be silenced.
This patch changes the code to always use to the start, which also
simplifies several calculations.

Takashi Iwai 0df63e44c3 [ALSA] Add O_APPEND flag support to PCM
Added O_APPEND flag support to PCM to enable shared substreams
among multiple processes.  This mechanism is used by dmix and

Takashi Iwai 3bf75f9b90 [ALSA] Clean up PCM codes (take 2)
- Clean up initialization and destruction of substream instance
  Now snd_pcm_open_substream() alone does most initialization jobs.
  Add pcm_release callback for cleaning up at snd_pcm_release_substream()
- Tidy up PCM oss code

Takashi Iwai 7c22f1aaa2 [ALSA] Remove snd_runtime_check() macro
Remove snd_runtime_check() macro.
This macro worsens the readability of codes.  They should be either
normal if() or removable asserts.

Also, the assert displays stack-dump, instead of only the last caller
pointer.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
