From 9af45ef5ab8ce4a13c553200dc15509441fbd68f Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 21 Jan 2013 17:34:21 +0900 Subject: [PATCH] f2fs: add comments of start_bidx_of_node The caller of start_bidx_of_node() should give proper node offsets which point only direct node blocks. Otherwise, it is a caller's bug. This patch adds comments to make it clear.
