Hello everyone:
I am a student interesting in linux filesystem, I have a problem about the replace of block number type to ext4_fsblk_t. Is it complete? Or has it passed all the test? Because I have found a place like this in linux-2.6.19-rc2/fs/ext4/inode.c
+struct buffer_head *ext4_bread(handle_t *handle, struct inode *inode,
+ int block, int create, int *err)
the block's type is not changed. Although I think it will bring no mistake, I doubt about why not change it. Thank you !

I also find many places where the block number type is not changed in namei.c and dir.c. Why?
Thank you to anyone who offer help

They are all file logical blocks, ext4_fsblk_t is for on disk blocks.
Takashi Sato has a patch to define all file logical blocks as
ext3_fileblk_t, it did not make to mainline before ext4 was forked.
Probably we should bring the to ext3/4 to clarify the confusions.
