directory /data/misc/apexdata so that directories below it
may be opened. It also gives that permission on the apex
data directories themselves.

Prefetching appears to have a slightly negative effect on boot time, and
actually makes boot time much worse when the available dm-bufio cache
shrinks. Since we anticipate the dm-bufio cache will shrink (because of
an increasing number of APEX dm-verity targets), disable prefetching
completely.
We've run this change on Pixel 2 since August, and haven't observed any
negative effects. Boot time slightly decreased. With the increased
amount of APEXes we already have, this should now result in an even more
significant boot time decrease.

Current linkerconfig targets for specific output file. However,
linkerconfig will generate more than 1 file based on APEX modules, so it
should take argument for target directory rather than target file. This
change updates linkerconfig's argument to point output directory.

sys.init.updatable_crashing_process_name setprops to make sure that

There are two namespaces from init - bootstrap and default - and those
will have different set of APEX modules. To support difference between
two namespaces, linker config should be generated per namespace and each
namespace should use its own linker configuration. As a first step of
the work, this change will create different mount point for each
namespace, and re-generate linker config after APEX mount from each
namespaces.

This is a partial revert of change
Idf851b3a42910e0ce8fdd75daea1cce91dd1aa98, and brings us back to the
state we shipped in Q.
The default behavior for now is that we want native daemons to use the
default sdcardfs view, as they did before. Zygote-spawned apps will then
get the correct view assigned to them as they get spawned.

Mount a tmpfs on top of it, and serve as a mirror of /data/data
and /data/user_de, which will be used when zygote forks and
overlay its CE and DE storage to prevent app can see other applications.
Also, changed /data/user/0 from symlink to bind mount, so
/data_mirror/data_ce/null can just bind to /data/user directly.

This should solve the problem of
`property:sys.usb.config=adb && property:sys.usb.configfs=0` action
being wrongly triggered during userspace reboot.

possible to normal boot sequence w.r.t adbd.

This creates the /data/misc/apexrollback directory which will
hold snapshots of DE_sys apex data directories (i.e. it will
hold backups of data from /data/misc/apexdata for particular
apexes).

This creates the directory /data/misc/apexdata, at the same time as other
directories under /data/misc. Then, when apexd has finished activating
APEXes, a directory is created under /data/misc/apexdata for every
APEX, with the same name as the APEX module name.
See go/apex-data-directories.
APEXes are discovered by scanning the /apex directory. It may be better
to delegate this process to a library, but it is proposed to defer that
change to a future CL.

Run this process as early as possible in the boot -- right
after its config has been parsed from the apex. This ensures
the sdk prop is set as early as it can be, should some other
early process need to look at it.
Note: this is unlikely to be the permanent way this gets run,
as it's only needed when apexes update.

lmkd: Support process types when registering a process
lmkd: Add library function to unregister a process
lmkd: Prepare lmkd to support connection from init process
lmkd: Restrict process record modifications to the client that created it
init should be able to register native services with lmkd so that they
can be killed when needed. Only processes with oom_score_adjust not
equal to the default -1000 will be registered with lmkd because with the
score that low the process is unkillable anyway.
Inform lmkd when a registered process is killed so that the record can be
removed.
Change init.rc to start lmkd during init phase so that it is there to
register other services.
Replace hardcoded oom_score_adj values with appropriate definitions.
