When vold starts up, there are lots of warnings like:
W vold : Failed to LOOP_GET_STATUS64 /dev/block/loop30: No such device or address
W vold : Failed to LOOP_GET_STATUS64 /dev/block/loop29: No such device or address
W vold : Failed to LOOP_GET_STATUS64 /dev/block/loop28: No such device or address
vold is iterating through all loop devices and unbinding the file from
any vold-managed ones.
It's expected that not all loop devices have a file bound to them,
however. On these, LOOP_GET_STATUS64 fails with ENXIO.
Don't print a warning in such cases.

Using the regular CreateDevice() variant with getDmDeviceByName() has a
race-condition that is documented in libdm/dm.h; instead, use the
variant with a timeout, which guarantees that the block device exists
when it returns.

We want various per-user directories to have their SELinux MLS level
set to restrict access from other users, as an improvement to user
isolation.
We extend vold_prepare_subdirs to implement this if a flag is
set. vold itself then sets the flag based on a new property,
ro.vold.level_from_user. This is to allow testing of further
incremental work to ensure system apps correctly handle the new
restriction on different devices rather than causing immediate
breakage. Eventually this will go away and the restriction will apply
everywhere.

Nothing defines CONFIG_HW_DISK_ENCRYPTION, so remove the unused code

A new interface, F2FS_IOC_SEC_TRIM_FILE, has been added to F2FS
filesystem to send secure discard command to a specific file,
not to block device. We can use this interface for better discard
command handling on a file basis.
[how to use F2FS_IOC_SEC_TRIM_FILE]
start: start offset in byte (should be aligned with 4096)
len: length in byte (should be aligned with 4096, except designating EOF)
-1 also means till EOF.
flags: F2FS_TRIM_FILE_DISCARD - sending secure discard command. If the
device doesn't support it, send normal
discard.
F2FS_TRIM_FILE_ZEROOUT - overwrite zero data in the file.

The name "pre_gki_level" is causing some confusion because not all
devices launching with Android R are subject to the GKI requirement.
(See b/161563110#comment11.) E.g., devices that use a 4.14-based kernel
are exempt from GKI. However, the encryption requirements still apply.
Just use __ANDROID_API_Q__ directly instead.
No change in behavior.

Block groups with EXT4_BG_BLOCK_UNINIT still have backup superblocks
(and backup block group descriptors). Fix EncryptInPlace to encrypt
these backup superblocks rather than leave them unencrypted.
Previously leaving the backup superblocks unencrypted didn't cause any
problems, but due to system/core commit 72abd7b246f7 ("Try to recover
corrupted ext4 /data with backup superblock") it is causing problems.

Use C++'s built-in mechanism for one-time initialization rather than
implement it ourselves in a way that isn't thread-safe.
(It doesn't *actually* need to be thread-safe, since all callers of this
run under ACQUIRE_CRYPT_LOCK. But that's not easy to verify.)
Test: booted Cuttlefish and checked log for the one-time message
"Detected support for FS_IOC_ADD_ENCRYPTION_KEY"
