When the android system is started, the size of the userdata file system is dynamically reset according to the size of the space of the userdata file system and the size of the reserved physical partition space of a memory (such as emmc), so that the optimal userdata space is obtained, the utilization rate of the userdata space is effectively improved and optimized, and meanwhile, the memory with different sizes and capacities is compatible on system software, so that the cost is saved for enterprises.
Partitioning the physical partition size of memory on hardware may be done as follows
Partition1for boot；
Partition2for boot.bak；
Partition3for cache；
Partition4for recovery；
Partition5for config；
Partition6for persist；
......
Partition last-1for system；
Partition last for userdata；
These physical partitions are logically unchangeable in software, with both start and end address locations fixed.
The android system divides the memory into corresponding logical partitions, corresponding to the corresponding physical partitions, the size of each partition is determined by the size of a file system written by the corresponding logical partition, and the size of each partition must be smaller than or equal to the size of the corresponding physical partition, otherwise, the file system cannot be programmed into the corresponding physical partition, or the file system can cross the boundary to the next partition during programming, and the file system is covered by the file systems of other partitions.

This step is to write all the file systems to each specified physical partition. And is not limited to this physical partition to which the userdata file system corresponds.
And C, starting the android system, and acquiring the size of a userdata file system in the mounted file system when the file system is mounted.
In this step, when the init process of the android system is initialized, after the file system is mounted, including all logical partitions, whether the file system is mounted is checked to be successful or not, at this time, whether the file system is time-consuming or not can be judged when the api of the fs_mgr module is called, and if yes, the size of the file system is read again.
And D, acquiring the actual capacity of the physical partition of userdata.
The size of the userdata physical partition of the proc/parts memory physical partition table is read in this step. The capacity size of the physical partition is obtained.
And E, calculating the size of the userdata which can be obtained practically, wherein the size of the userdata=the size of the userdata physical partition-the size of the physical space to be reserved.
And F, if the actually available userdata size is larger than the existing userdata file system size, resetting the existing userdata file system to the available userdata size.
Optionally, resetting the userdata file system in step F may be implemented by calling the restore 2fs module.
Optionally, the implementation of the steps C to F flows is implemented by modifying the check_fs of the fs_mgr module.
