发现在内核在在:page_counter_try_charge中的page_counter_try_charge中已经把page给接受了,除非memcg->memory->limit设置了,只有这个时候内存才被会直接回收,如果没有设置memory.limit_in_bytes,那么这里就不会设置就不会走到下面的直接回收的过程!不过话说回来,这里的memsw又是啥 1 2 3 4 5 6 7 8 9 1902...

The default units are bytes, but you can also specify a k or K, m or M, and g or G suffix for kilobytes, megabytes, and gigabytes respectively. A value of -1 removes the limit. The soft limit should be lower than the hard-limit value of memory.limit_in_bytes as the hard limit...
