zram: add `compact` sysfs entry to documentation
We currently don't support zram on-demand device creation. The only way
to have N zram devices is to specify num_devices module parameter (default
value 1). That means that if, for some reason, at some point, user wants
to have N + 1 devies he/she must umount all the existing devices, unload
the module, load the module passing num_devices equals to N + 1.
This patchset introduces zram-control sysfs class, which has two sysfs
attrs:
- hot_add -- add a new zram device
- hot_remove -- remove a specific (device_id) zram device
Usage example:
# add a new specific zram device
cat /sys/class/zram-control/hot_add
1
# remove a specific zram device
echo 4 > /sys/class/zram-control/hot_remove
This patch (of 10):
Briefly describe missing `compact` sysfs entry.
