Now accessible via zram<id>/io_stat node. What: /sys/block/zram<id>/failed_reads Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The failed_reads file is read-only and specifies the number of failed reads happened on this device.

What: /sys/block/zram<id>/notify_free Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The notify_free file is read-only. Depending on device usage scenario it may account a) the number of pages freed because of swap slot free notifications or b) the number of pages freed because of REQ_DISCARD requests sent by bio. The former ones are sent to a swap block device when a swap slot is freed, which implies that this disk is being used as a swap disk. The latter ones are sent by filesystem mounted with discard option, whenever some data blocks are getting discarded. Now accessible via zram<id>/io_stat node. What: /sys/block/zram<id>/zero_pages Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The zero_pages file is read-only and specifies number of zero filled pages written to this disk. No memory is allocated for such pages. Now accessible via zram<id>/mm_stat node. What: /sys/block/zram<id>/orig_data_size Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The orig_data_size file is read-only and specifies uncompressed size of data stored in this disk. This excludes zero-filled pages (zero_pages) since no memory is allocated for them. Unit: bytes Now accessible via zram<id>/mm_stat node. What: /sys/block/zram<id>/compr_data_size Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The compr_data_size file is read-only and specifies compressed size of data stored in this disk. So, compression ratio can be calculated using orig_data_size and this statistic. Unit: bytes Now accessible via zram<id>/mm_stat node. What: /sys/block/zram<id>/mem_used_total Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The mem_used_total file is read-only and specifies the amount of memory, including allocator fragmentation and metadata overhead, allocated for this disk. So, allocator space efficiency can be calculated using compr_data_size and this statistic. Unit: bytes Now accessible via zram<id>/mm_stat node. What: /sys/block/zram<id>/mem_used_max Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The mem_used_max file is read/write and specifies the amount of maximum memory zram have consumed to store compressed data. For resetting the value, you should write "0". Otherwise, you could see -EINVAL. Unit: bytes Downgraded to write-only node: so it's possible to set new value only; its current value is stored in zram<id>/mm_stat node. What: /sys/block/zram<id>/mem_limit Date: August 2015 Contact: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Description: The mem_limit file is read/write and specifies the maximum amount of memory ZRAM can use to store the compressed data. The limit could be changed in run time and "0" means disable the limit. No limit is the initial state. Unit: bytes Downgraded to write-only node: so it's possible to set new value only; its current value is stored in zram<id>/mm_stat node.
