zswap: only save zswap header when necessary

2018-02-01T01:18:39Z

We waste sizeof(swp_entry_t) for zswap header when using zsmalloc as zpool driver because zsmalloc doesn't support eviction. Add zpool_evictable() to detect if zpool is potentially evictable, and use it in zswap to avoid waste memory for zswap header.

zpool: remove redundant zpool->type string, const-ify zpool_get_type

2015-11-07T01:50:42Z

Make the return type of zpool_get_type const; the string belongs to the zpool driver and should not be modified. Remove the redundant type field in the struct zpool; it is private to zpool.c and isn't needed since ->driver->type can be used directly. Add comments indicating strings must be null-terminated.

zpool: add zpool_has_pool()

2015-09-10T20:29:01Z

This series makes creation of the zpool and compressor dynamic, so that they can be changed at runtime. This makes using/configuring zswap easier, as before this zswap had to be configured at boot time, using boot params. This uses a single list to track both the zpool and compressor together, although Seth had mentioned an alternative which is to track the zpools and compressors using separate lists. In the most common case, only a single zpool and single compressor, using one list is slightly simpler than using two lists, and for the uncommon case of multiple zpools and/or compressors, using one list is slightly less simple (and uses slightly more memory, probably) than using two lists. This patch (of 4): Add zpool_has_pool() function, indicating if the specified type of zpool is available (i.e. zsmalloc or zbud). This allows checking if a pool is available, without actually trying to allocate it, similar to crypto_has_alg(). This is used by a following patch to zswap that enables the dynamic runtime creation of zswap zpools.
