ALSA: Fix card refcount unbalance

2012-11-08T13:36:18Z

There are uncovered cases whether the card refcount introduced by the commit a0830dbd isn't properly increased or decreased: - OSS PCM and mixer success paths - When lookup function gets NULL This patch fixes these places.

ALSA: Avoid endless sleep after disconnect

2012-10-30T10:07:15Z

When disconnect callback is called, each component should wake up sleepers and check card->shutdown flag for avoiding the endless sleep blocking the proper resource release. Cc: Signed-off-by: Takashi Iwai

ALSA: Add a reference counter to card instance

2012-10-30T10:07:10Z

For more strict protection for wild disconnections, a refcount is introduced to the card instance, and let it up/down when an object is referred via snd_lookup_*() in the open ops. The free-after-last-close check is also changed to check this refcount instead of the empty list, too. Reported-by: Matthieu CASTET Cc: Signed-off-by: Takashi Iwai

ALSA: PCM: Fix some races at disconnection

2012-10-30T10:06:48Z

Fix races at PCM disconnection: - while a PCM device is being opened or closed - while the PCM state is being changed without lock in prepare, hw_params, hw_free ops Reported-by: Matthieu CASTET Cc: Signed-off-by: Takashi Iwai

mm: kill vma flag VM_RESERVED and mm->reserved_vm counter

2012-10-09T07:22:19Z

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

ALSA: pcm - Add proper state checks to snd_pcm_drain()

2012-05-21T10:03:54Z

The handling for some PCM states is missing for snd_pcm_drain(). At least, XRUN streams should be simply dropped to SETUP, and a few initial invalid states should be rejected. Signed-off-by: Takashi Iwai

ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link()

2012-03-15T06:36:00Z

GFP_ATOMIC is used in snd_pcm_link() just because the kmalloc is called inside a lock. Since this function isn't too critical for speed and is rarely called in practice, better to allocate the chunk at first before spinlock and free it in error paths, so that GFP_KERNEL can be used.

sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21Z

Lots of sound drivers were getting module.h via the implicit presence of it in but we are going to clean that up. So fix up those users now. Signed-off-by: Paul Gortmaker
