4 Description:
5                 /sys/kernel/mm/frontswap/ contains a number of files which
6                 record a count of various frontswap operations (sum across
7                 all swap devices):
8                         succ_puts
9                         failed_puts
10                         gets
11                         flushes
12                 In addition, reading the curr_pages file shows how many
13                 pages are currently contained in frontswap and writing this
14                 file with an integer performs a "partial swapoff", reducing
15                 the number of frontswap pages to that integer if memory
16                 constraints permit.
