[PATCH] page_frag: Recover from memory pressure (Matthew Wilcox)

https://lkml.kernel.org/r/20201105042140.5253-1-willy@infradead.org

After an extreme memory pressure, some non-essential packets can be dropped because the ‘page_frag’ allocator do the drops to recover from the memory pressure but it doesn’t change back the behavior even after the recovery. This commit fixes this.
