linux – 我怎么知道哪个进程使用swap？

[a] /proc/meminfo – This file reports statistics about memory usage on
the system. It is used by free to report the amount of free and used
memory (both physical and swap) on the system as well as the shared
memory and buffers used by the kernel. You can also use free,vmstat
and other tools to find out the same information.

[b]
/proc/${PID}/smaps,/proc/${PID}/status,and /proc/${PID}/stat : Use
these files to find information about memory,pages and swap used by
each process using its PID.

[c] smem – This command (python script) reports memory usage with
shared memory divided proportionally.
