Lines Matching full:writeback

252  * Attempt writeback with the following steps:
260       this will either trigger writeback if it's enabled, or reclamation
261       will fail if writeback is disabled as there isn't enough zswap space.
308 	 * If writeback is enabled, trying to reclaim memory now will trigger a
309 	 * writeback as zswap.max is half of what was needed when reclaim ran the first time.
310 	 * If writeback is disabled, memory reclaim will fail as zswap is limited and
311 	 * it can't writeback to swap.
335 	/* Verify that zswap writeback occurred only if writeback was enabled */
349 /* Test to verify the zswap writeback path */
