[PATCH] binder: Use kmem_cache for binder_thread

2019-08-28 Thread Peikan Tsai
Hi, The allocated size for each binder_thread is 512 bytes by kzalloc. Because the size of binder_thread is fixed and it's only 304 bytes. It will save 208 bytes per binder_thread when use create a kmem_cache for the binder_thread. Signed-off-by: Peikan Tsai --- drivers/android/binder.c | 16 ++
