ASoC: Tegra: wm8903 machine driver: Allow re-insertion of module

Two issues were preventing module snd-soc-tegra-wm8903.ko from being
removed and re-inserted:

a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must
   be freed before snd_soc_unregister_card() is called, because that
   triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which
   then fails if any of the GPIOs are in use. To solve this, free all GPIOs
   first, so the code doesn't care where they come from.

b) We need to call snd_soc_jack_free_gpios() to match the call to
   snd_soc_jack_add_gpios() during initialization. Without this, the
   call to snd_soc_jack_add_gpios() fails during any subsequent modprobe
   and initialization, since the GPIO and IRQ are already registered. In
   turn, this causes the headphone state not to be monitored, so the
   headphone is assumed not to be plugged in, and the audio path to it is

13 years agovfs: optimize inode cache access patterns

vfs: optimize inode cache access patterns

The inode structure layout is largely random, and some of the vfs paths
really do care.  The path lookup in particular is already quite D$
intensive, and profiles show that accessing the 'inode->i_op->xyz'
fields is quite costly.

We already optimized the dcache to not unnecessarily load the d_op
structure for members that are often NULL using the DCACHE_OP_xyz bits
in dentry->d_flags, and this does something very similar for the inode
ops that are used during pathname lookup.

It also re-orders the fields so that the fields accessed by 'stat' are
together at the beginning of the inode structure, and roughly in the
order accessed.

The effect of this seems to be in the 1-2% range for an empty kernel
"make -j" run (which is fairly kernel-intensive, mostly in filename
lookup), so it's visible.  The numbers are fairly noisy, though, and
likely depend a lot on exact microarchitecture.  So there's more tuning
to be done.

Boaz Harrosh [Fri, 5 Aug 2011 22:06:04 +0000 (15:06 -0700)]
exofs: ios: Move to a per inode components & device-table

Exofs raid engine was saving on memory space by having a single layout-info,
single pid, and a single device-table, global to the filesystem. Then passing
a credential and object_id info at the io_state level, private for each
inode. It would also devise this contraption of rotating the device table
view for each inode->ino to spread out the device usage.

This is not compatible with the pnfs-objects standard, demanding that
each inode can have it's own layout-info, device-table, and each object
component it's own pid, oid and creds.

So: Bring exofs raid engine to be usable for generic pnfs-objects use by:

* Define an exofs_comp structure that holds obj_id and credential info.

* Break up exofs_layout struct to an exofs_components structure that holds a
  possible array of exofs_comp and the array of devices + the size of the
  arrays.

* Add a "comps" parameter to get_io_state() that specifies the ids creds
  and device array to use for each IO.

  This enables to keep the layout global, but the device-table view, creds
  and IDs at the inode level. It only adds two 64bit to each inode, since
  some of these members already existed in another form.

* ios raid engine now access layout-info and comps-info through the passed
  pointers. Everything is pre-prepared by caller for generic access of
  these structures and arrays.

At the exofs Level:

* Super block holds an exofs_components struct that holds the device
  array, previously in layout. The devices there are in device-table
  order. The device-array is twice bigger and repeats the device-table
  twice so now each inode's device array can point to a random device
  and have a round-robin view of the table, making it compatible to
  previous exofs versions.

* Each inode has an exofs_components struct that is initialized at
  load time, with it's own view of the device table IDs and creds.
  When doing IO this gets passed to the io_state together with the
  layout.

While preforming this change. Bugs where found where credentials with the
wrong IDs where used to access the different SB objects (super.c). As well
as some dead code. It was never noticed because the target we use does not
check the credentials.

So add a new exofs_get_rw_state() API for use when

The major change to this is that now we need to call
exofs_get_io_state later at inode.c::read_exec and
