From 28ecb60906e86e74e9ad4ac7e0218d8631e73a94 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Wed, 17 Mar 2010 13:31:04 +0000 Subject: [PATCH] Btrfs: use add_to_page_cache_lru, use __page_cache_alloc Pagecache pages should be allocated with __page_cache_alloc, so they obey pagecache memory policies. add_to_page_cache_lru is exported, so it should be used. Benefits over using a private pagevec: neater code, 128 bytes fewer stack used, percpu lru ordering is preserved, and finally don't need to flush pagevec before returning so batching may be shared with other LRU insertions.
