From Shawn Heo's patch:
Ext4 introduced reserved clusters to prevent costly zeroout, or
unexpected ENOSPC. The size is 2% or 4096 clusters, whichever
is smaller (http://lwn.net/Articles/546473/).
So, we need to allocate additionally this amount of free space
to asecs when vold create asec images. This is required when
Android runs on Linux kernel 3.10 or later.

ASECs formatted as ext4 can now be resized using vdc asec resize.
Refactored some common code.
Requires resize2fs.

The code was using encrypted_upto == 0 as an indicator that encryption
has succeeded. This meant that if no encryption happened, we would reboot
continually.
We now set encrypted_upto to fs_size when encryption is complete.
Also don't start to encrypt unless we are at 10% power. Stop when we
get to 5% power. This should lead to partial encryptions only very
rarely.

Changed ext4 to be 4kb aligned, and fat to be 32kb aligned.
Fixed issue that could potentially cause unencrypted ext4
ASECS to overwrite the ASEC super block when filled.

Add support for the storage with non-sequential partition index
Ex: if using extended partition, the index of the partition will be greater than 5

Must limit vold calls to fs_mkdirs() only when the volume is mounted.
If NOT, it will trigger selinux warning as follows.

Switching the kernel to the new sysfs layout (unselecting
CONFIG_SYSFS_DEPRECATED) complicates VolD block device recognition.
The uevents are reporting full specific paths, such as:
/devices/pci0000:0e/0000:0e:18.0/mmc_host/mmc0/mmc0:1234/block/mmcblk0
Because the full device path may contain variable IDs (in this MMC
case "1234") using full path entries in fstab does not work. Android
supports partial matches but only as a prefix at the beginning of the
path.
This patch adds support for matching shell wildcard patterns via
fnmatch(). The prefix matching rule is preserved, but if it is
detected a warning is issued.
