So report it in the right number. This can be easily exposed by the following command: echo foo > blah; du -hc blah; sync; du -hc blah Reported-by: Eric Sandeen Signed-off-by: Tao Ma Signed-off-by: "Theodore Ts'o" --- diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index 7bccdf32a32c..fc083e87c231 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -4301,7 +4301,8 @@ int ext4_getattr(struct vfsmount *mnt, struct dentry *dentry, * will return the blocks that include the delayed allocation * blocks for this file. */ - delalloc_blocks = EXT4_I(inode)->i_reserved_data_blocks; + delalloc_blocks = EXT4_C2B(EXT4_SB(inode->i_sb), + EXT4_I(inode)->i_reserved_data_blocks); stat->blocks += (delalloc_blocks << inode->i_sb->s_blocksize_bits)>>9; return 0;
