Interesting is the randwrite harddisk test is improved too. This might be because swapin readahead need allocate extra memory, which further tights memory pressure, so more swapout/swapin. This patch depends on readahead-fault-retry-breaks-mmap-file-read-random-detection.patch V2->V3: move swapra_miss to 'struct anon_vma' as suggested by Konstantin. V1->V2: 1. Move the swap readahead accounting to separate functions as suggested by Riel. 2. Enable the logic only with CONFIG_SWAP enabled as suggested by Minchan. Signed-off-by: Shaohua Li <shli@xxxxxxxxxxxx>
