From bf39c00a9a7f3cdb5ce7d6695d9f044daf8f0b53 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 22 Jan 2014 20:41:57 +0900 Subject: f2fs: drop obsolete node page when it is truncated If a node page is trucated, we'd better drop the page in the node_inode's page cache for better memory footprint.
