What: /sys/block/zram<id>/notify_free
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The discard file is read-only and specifies the number of
discard requests received by this device. These requests
provide information to block device regarding blocks which are
no longer used by filesystem.
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.

Description:
The io_stat file is read-only and accumulates device's I/O
statistics not accounted by block layer. For example,
failed_reads, failed_writes, etc. File format is similar to
block layer statistics file format.

Description:
The mm_stat file is read-only and represents device's mm
statistics (orig_data_size, compr_data_size, etc.) in a format
similar to block layer statistics file format.

/*
* z3fold.c
*
* This implementation is based on zbud written by Seth Jennings.
*
* z3fold is an special purpose allocator for storing compressed pages. It
* can store up to three compressed pages per page which improves the
* compression ratio of zbud while retaining its main concepts (e. g. always
* storing an integral number of objects per page) and simplicity.
* It still has simple and deterministic reclaim properties that make it
* preferable to a higher density approach (with no requirement on integral
* number of object per page) when reclaim is used.
*
* As in zbud, pages are divided into "chunks". The size of the chunks is
* fixed at compile time and is determined by NCHUNKS_ORDER below.
*
* z3fold doesn't export any API and is meant to be used via zpool API.

* z3fold_reclaim_page() - evicts allocations from a pool page and frees it
* @pool: pool from which a page will attempt to be evicted

*
* z3fold reclaim is different from normal system reclaim in that it is done

* information on how the allocations are organized within each z3fold page.
* This has the potential to create interesting locking situations between
* z3fold and the user, however.
*
* To avoid these, this is how z3fold_reclaim_page() should be called:
* The user detects a page should be reclaimed and calls z3fold_reclaim_page().
* z3fold_reclaim_page() will remove a z3fold page from the pool LRU list and
* call the user-defined eviction handler with the pool and handle as
* arguments.
*
* If the handle can not be evicted, the eviction handler should return
* non-zero. z3fold_reclaim_page() will add the z3fold page back to the
* appropriate list and try the next z3fold page on the LRU up to
* a user defined number of retries.
*
* If the handle is successfully evicted, the eviction handler should
* return 0 _and_ should have called z3fold_free() on the handle. z3fold_free()
* contains logic to delay freeing the page if the page is under reclaim,
* as indicated by the setting of the PG_reclaim flag on the underlying page.
*
* If all buddies in the z3fold page are successfully evicted, then the
* z3fold page can be freed.
