[PATCH] sched: Use kmem_cache_zalloc() instead of kmem_cache_alloc() with flag GFP_ZERO.

From: Yi Wang
Date: Wed Feb 12 2020 - 04:55:05 EST


From: Huang Zijiang <huang.zijiang@xxxxxxxxxx>

Use kmem_cache_zalloc instead of manually setting kmem_cache_alloc
with flag GFP_ZERO since kzalloc sets allocated memory
to zero.

Change in v2:
add indation
