++Subject: [PATCH] fs, seq_file: fallback to vmalloc instead of oom kill
++ processes
++
++Since commit 058504edd026 ("fs/seq_file: fallback to vmalloc allocation"),
++seq_buf_alloc() falls back to vmalloc() when the kmalloc() for contiguous
++memory fails.  This was done to address order-4 slab allocations for
++reading /proc/stat on large machines and noticed because
++PAGE_ALLOC_COSTLY_ORDER < 4, so there is no infinite loop in the page
++allocator when allocating new slab for such high-order allocations.
++
++Contiguous memory isn't necessary for caller of seq_buf_alloc(), however.
++Other GFP_KERNEL high-order allocations that are <=
++PAGE_ALLOC_COSTLY_ORDER will simply loop forever in the page allocator and
++oom kill processes as a result.
++
++We don't want to kill processes so that we can allocate contiguous memory
++in situations when contiguous memory isn't necessary.
++
++This patch does the kmalloc() allocation with __GFP_NORETRY for high-order
++allocations.  This still utilizes memory compaction and direct reclaim in
++the allocation path, the only difference is that it will fail immediately
++instead of oom kill processes when out of memory.
