- Emergency shutdown just marks the fs as clean while leaving fs
in the middle of any state. Do not use it anymore.
- Changed android_reboot to set sys.powerctl property so that
all shutdown can be done by init.
- Normal reboot sequence changed to
1. Terminate processes (give time to clean up). And wait for
completion based on ro.build.shutdown_timeout.
Default value (when not set) is changed to 3 secs. If it is 0, do not
terminate processes.
2. Kill all remaining services except critical services for shutdown.
3. Shutdown vold using "vdc volume shutdown"
4. umount all emulated partitions. If it fails, just detach.
Wait in step 5 can handle it.
5. Try umounting R/W block devices for up to max timeout.
If it fails, try DETACH.
If umount fails to complete before reboot, it can be detected when
system reboots.
6. Reboot
- Log shutdown time and umount stat to log so that it can be collected after reboot
- To umount emulated partitions, all pending writes inside kernel should
be completed.
- To umount /data partition, all emulated partitions on top of /data should
be umounted and all pending writes should be completed.
- umount retry will only wait up to timeout. If there are too many pending
writes, reboot will discard them and e2fsck after reboot will fix any file system
issues.

Add reading of vendor file-system config files
/oem/etc/fs_config_dirs and /oem/etc/fs_config_files.
Order of interpretation (for dirs and files respectively):
- /system/etc/fs_config_dirs or /system/etc/fs_config_files
- /vendor/etc/fs_config_dirs or /vendor/etc/fs_config_files
- /oem/etc/fs_config_dirs or /oem/etc/fs_config_files
- internal android_dirs[] or android_files[] structures.
No restrictions are placed on the oem file-system config files,
although the developer is advised to restrict the scope to the /oem
file-system since the intent is to provide support only for
customized portions of oem.img.

The qtaguid_tagSocket() function tags a network socket by passing a
reference to the given socket to the qtaguid kernel module. The module
will keep the socket alive even if the process calls close() on said
socket. In this scenario, the socket object would not be destroyed
even if all the file descriptor.
While this is at least a memory leak, it plays bad with epoll(7)
if you also didn't remove the socket from the epoll fd before closing
since epoll will not notice that the socket was closed and there is no
way to remove the socket from epoll after it was closed.
This patch updates the documentation to explicitly mention that the
socket must be untag before closing or bad things happen.

These two Soong product_variables were usually controlled by
ENABLE_CPUSETS and ENABLE_SCHEDBOOST in BoardConfig.mk. This change
turns the build time variables into runtime decision by checking if
a special file, "tasks", can be found under the mount points,
/dev/cpuset and /dev/stune, for cpusets and schedboost, respectively.
That special file only exists when the corresponding Linux kernel
configurations, CONFIG_CPUSETS and CONFIG_SCHEDTUNE, are set.
Bug: 34726944
Test: Tested on Sailfish with following configurations
neither cpuset nor schedtune enabled in the kernel
cpuset enabled, but schedtune disabled in the kernel

CAP_SYS_PTRACE is needed to ptrace processes that have capabilities
greater than their bounding set. Eventually, this will still be an

Moved headers from include/libcutils and include/liblog to
libcutils/include and liblog/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.
Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.
Also added liblog_vndk_headers that exports a special log/log.h for
VNDK.
Moved headers of libcutils to libcutils_headers. They should be used
by modules for header-only inlines. Added libcutils_headers as
dependency of libcutils.
Added libcutils_vndk_headers that exports a special cutils/log.h
deprecating usage of the file. A later CL will deprecate the one in
libcutils_headers
Test: Add above libs to shared lib of local module

To quickly answer the question of "how much data is a UID using?" we

Some of Android componets e.g. init have migrated to use base/logging to get rid
of klog utilities. However, without explicit initilization, the default
klog_level is set to 3 which masks the logwrap output.
This patch sets default klog_level to KLOG_INFO_LEVEL to make
android_fork_execvp_ext log available.
