This change introduces an aged idle interface to the existing
idle sysfs file for zram.
When CONFIG_ZRAM_MEMORY_TRACKING is enabled the idle file
now also accepts an integer argument. This integer is the
age (in seconds) of pages to mark as idle. The idle file
still supports 'all' as it always has. This new approach
allows for much more control over which pages get marked
as idle.
v3 -> v4:
- Remove base10 restriction.
v2 -> v3:
- Correct unused variable warning when
CONFIG_ZRAM_MEMORY_TRACKING is not enabled.
v1 -> v2:
- Switch to using existing idle file.
- Dont compare ktime directly.
