0f76570677 Avoid exception caused by cgroup writeback feature 
The cgroup writeback feature requires cooperation
between memcgs and blkcgs.
To avoid exceptions, we should add_task for blkcg before
memcg(push BlkIo before Mem).

cd7e737149 lib: fix compiling error for type i8 in aarch64 environment 
c_char is equal to i8 on x86, but it is equal to u8 on arm arch,
so we need to use type c_char instead of i8 to avoid compiling error.
