From 3e6d0b4d9c1cd3bbe5bacbf9d6de682be2bce8e4 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 6 Jul 2016 14:13:07 +0800 Subject: [PATCH] f2fs: fix incorrect f_bfree calculation in ->statfs As manual described, f_bfree indicates total free blocks in fs, in f2fs, it includes two parts: visible free blocks and over-provision blocks. This patch corrrects the calculation. fsblkcnt_t f_bfree; /* free blocks in fs */ Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim --- fs/f2fs/super.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/f2fs/super.c b/fs/f2fs/super.c index 2bac9171d2c3..edd1b356d667 100644 --- a/fs/f2fs/super.c +++ b/fs/f2fs/super.c @@ -816,7 +816,7 @@ static int f2fs_statfs(struct dentry *dentry, struct kstatfs *buf) buf->f_bsize = sbi->blocksize; buf->f_blocks = total_count - start_count; - buf->f_bfree = buf->f_blocks - valid_user_blocks(sbi) - ovp_count; + buf->f_bfree = user_block_count - valid_user_blocks(sbi) + ovp_count; buf->f_bavail = user_block_count - valid_user_blocks(sbi); buf->f_files = sbi->total_node_count - F2FS_RESERVED_NODE_NUM;
