This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.Modified-by: Ingo Molnar

Modules: ALSA sequencer
Reduce the maximum possible number of global clients to 16 to make
more numbers available for card clients, and allow dynamically allocated
card client numbers to share the same range as application client
numbers to make sure that all 32 cards can be used at the same time.Signed-off-by: Clemens Ladisch
-
All users of snd_seq_create_kernel_client() have to set the client name
anyway, so we can just pass the name as parameter. This relieves us
from having to muck around with a struct snd_seq_client_info in these
cases.Signed-off-by: Clemens Ladisch
-
The fields of struct snd_seq_client_callback either aren't used or are
always set to the same value, so we can get rid of it altogether.Signed-off-by: Clemens Ladisch

This patch contains the following possible cleanups:
- pci/hda/hda_proc.c should #include 'hda_local.h' for including the
prototype of it's global function snd_hda_codec_proc_new()
- core/rawmidi.c: make the needlessly global and EXPORT_SYMBOL'ed

When the output buffer size is changed, runtime->avail must be
adjusted to the new size; otherwise, draining of a bigger buffer would
appear to fail because avail does not reach buffer_size.Signed-off-by: Clemens Ladisch

With dynamic minor numbers, we can increase the number of sound cards.
This requires that the sequencer client numbers of some kernel drivers
are allocated dynamically, too.Signed-off-by: Clemens Ladisch
-
Modules: ALSA sequencer,Generic drivers
To allow increasing the maximum number of sound cards, we have to limit
the number of sequencer clients per card because client numbers are
still allocated statically.Reducing the number of clients to four limits the number of sequencer
MIDI ports to 1024 per card.Signed-off-by: Clemens Ladisch

Instead of storing the pointers to the device-specific structures in an
array, put them into the struct snd_minor, and look them up dynamically.This makes the device type modules independent of the minor number
encoding.Signed-off-by: Clemens Ladisch
-
Modules: ALSA Core
Store the snd_minor structure pointers in one array instead of using a
separate list for each card. This simplifies the mapping from device
files to minor struct by removing the need to know about the encoding
of the card number in the minor number.Signed-off-by: Clemens Ladisch
-
Instead of a comment string, store the device type in the snd_minor
structure. This makes snd_minor more flexible, and has the nice side
effect that we don't need anymore to create a separate snd_minor
template for registering a device but can pass the file_operations
directly to snd_register_device().Signed-off-by: Clemens Ladisch

Earlier I unifdefed PageCompound, so that snd_pcm_mmap_control_nopage and
others can give out a 0-order component of a higher-order page, which won't
be mistakenly freed when zap_pte_range unmaps it. But many Bad page states
reported a PG_reserved was freed after all: I had missed that we need to
say __GFP_COMP to get compound page behaviour.Some of these higher-order pages are allocated by snd_malloc_pages, some by
snd_malloc_dev_pages; or if SBUS, by sbus_alloc_consistent - but that has
no gfp arg, so add __GFP_COMP into its sparc32/64 implementations.I'm still rather puzzled that DRM seems not to need a similar change.
