[PATCH 0/2] mm: Explicitly check & doc fragsz limit

[Haiyang Zhang]

The page frag allocator is not designed for fragsz > PAGE_SIZE.
Explicitly check it in the function & document the fragsz limit.

Haiyang Zhang (2):
  mm: page_frag: Check fragsz at the beginning of __page_frag_alloc_align()
  docs/mm: Specify page frag size is not bigger than PAGE_SIZE
