From 3c64298579a1343cbdf3d2f17adf774a58546aae Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Thu, 26 Feb 2015 07:57:21 +0800 Subject: [PATCH] f2fs: fix the number of orphan inode blocks cp_pack_start_sum is calculated in do_checkpoint and is equal to cpu_to_le32(1 + cp_payload_blks + orphan_blocks). The number of orphan inode blocks is take advantage of by recover_orphan_inodes to readahead meta pages and recovery inodes. However, current codes forget to reduce the number of cp payload blocks when calculate the number of orphan inode blocks. This patch fix it.
