From d6d4f1cb912d9bcf988a529d0934568d4550f7b5 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 12 Mar 2015 17:04:24 +0800 Subject: f2fs: fix to check current blkaddr in __allocate_data_blocks In __allocate_data_blocks, we should check current blkaddr which is located at ofs_in_node of dnode page instead of checking first blkaddr all the time. Otherwise we can only allocate one blkaddr in each dnode page. Fix it.
