mm/zswap: refactor the get/put routines
The refcount routine was not fit the kernel get/put semantic exactly,
There were too many judgement statements on refcount and it could be
minus.
This patch does the following:
- move refcount judgement to zswap_entry_put() to hide resource free function.
- add a new function zswap_entry_find_get(), so that callers can use
easily in the following pattern:
zswap_entry_find_get
.../* do something */
zswap_entry_put
- to eliminate compile error, move some functions declaration
This patch is based on Minchan Kim <minchan@kernel.org> 's idea and suggestion.
