Commit 597d795a ('mm: do not allocate page->ptl dynamically, if spinlock_t fits to long') restructures some allocators that are compiled even if USE_SPLIT_PTLOCKS arn't used. It results in compilation failure: mm/memory.c:4282:6: error: 'struct page' has no member named 'ptl' mm/memory.c:4288:12: error: 'struct page' has no member named 'ptl' Add in the missing ifdef. Fixes: 597d795a ('mm: do not allocate page->ptl dynamically, if spinlock_t fits to long') Signed-off-by:
