      Add f2fs support for private volumes. · d0640f63
      Jeff Sharkey authored 
      When formatting volumes, pass along fsType string which can be "auto"
to let the volume select the best choice.  For now, private volumes
assume that MMC devices (like SD cards) are best off using f2fs when
both kernel support and tools are present, otherwise fall back to
ext4.  Use blkid when mounting to pick the right set of tools.

Move filesystem utility methods into namespaces and place in separate
directory to be more organized.

      Move crypt commands to a different listener in vold · d0b4295c
      Paul Lawrence authored 
      In order to prevent this bug from happening, we must allow vold cryptfs
commands to complete while a long running mount is underway.

While waiting for vold to be changed to a binder interface, we will simply
create two listeners, one for cryptfs and one for everything else.

      Useful for transforming a secondary SD card slot into a primary SD
card slot without doing a completely different lunch target.

      Initial pass at storage benchmarks. · 5a6bfca1
      Jeff Sharkey authored 
      Now that we're offering to store private app data on adopted storage
devices, the performance of those devices is much more important to
overall user experience.

To help set user expectations, this change offers to execute a
real-world benchmark on a storage device, returning a metric that can
be used to compare internal and external storage.  The benchmark is
generated from the strace-instrumented storage access patterns of
typical apps.

A typical device completes the benchmark in under two seconds on
internal storage, a UHS-3 SD card is even faster (!), but a very slow
Class 4 SD card takes about 30 seconds to complete, giving us a clear
signal.

The measured benchmark numbers are logged along with information
about the storage device, such as manufacturer, model, etc.  Card
serial numbers are scrubbed from output.

      Migrate primary external storage. · 1d6fbcc3
      Jeff Sharkey authored 
      When requested, kick off a thread that will migrate storage contents
between two locations.  This is performed in several steps that
also interact with the framework:

1. Take old and new volumes offline during migration
2. Wipe new location clean (10% of progress)
3. Copy files from old to new (60% of progress)
4. Inform framework that move was successful so it can persist
5. Wipe old location clean (15% of progress)

Derives a hacky progress estimate by using a rough proxy of free
disk space changes while a cp/rm is taking place.

Add new internal path for direct access to volumes to bypass any
FUSE emulation overhead, and send it to framework.  Remove mutex
around various exec calls since setexeccon() is already per-thread.

      Wider volume mutation lock, move force adoptable. · c8e04c5a
      Jeff Sharkey authored 
      We eventually should move back to per-disk locks, but use a giant
lock to keep development rolling forward.  Also move force adoptable
flag to framework since, since encrypted devices don't have persisted
properties loaded early during boot.

      Volumes know parent disks; unsupported disks. · f1b996df
      Jeff Sharkey authored 
      This is cleaner and more direct than the reverse of having the disk
publish child volume membership.  Rename state constants to match
public API.  Add state representing bad removal.  Make it clear that
volume flags are related to mounting.

Send new unsupported disk event when we finish scanning an entire
disk and have no meaningful volumes.
