Message-Id: <1328025496-3521-1-git-send-email-tm@tao.ma> Date: Tue, 31 Jan 2012 23:58:16 +0800 From: Tao Ma <tm@....ma> To: linux-ext4@...r.kernel.org Cc: sandeen@...hat.com, "Theodore Ts'o" <tytso@....edu> Subject: [PATCH] ext4: let getattr report the right blocks in delalloc+bigalloc. From: Tao Ma <boyu.mt@...bao.com> In delayed allocation, i_reserved_data_blocks now indicates clusters, not blocks. 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 Cc: "Theodore Ts'o" <tytso@....edu> Reported-by: Eric Sandeen <sandeen@...hat.com> Signed-off-by: Tao Ma <boyu.mt@...bao.com> --- fs/ext4/inode.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index feaa82f..a5eb8c6 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -4200,7 +4200,8 @@ 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; -- 1.7.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
