poll umount completion from /proc/mounts
- umount operation is asynchronous except for root partition.
Returning from umount does not guarantee completion of
umount. Poll /proc/mounts to confirm completion of umount.
- Treat all devices mounting to /data as emulated devices. This is
future proof when fs other than sdcardfs is used.
- Drop quota sync from sync step. There is no differences in
frequencies of quota error.
- Run umount in reverse order from mounting order so that any
hidden dependency can be auto-resolved.
- Add dump of lsof and /proc/mounts when umount fails. lsof only runs
when selinux is toggled into permissive mode. The dump is enabled
only for non-user build.
- Keep logcat until vold shutdown in case vold has any error to report.
