ext4: Introduce ext4_lblk_t
This patch adds a new data type ext4_lblk_t to represent the logical file blocks. This is the preparatory patch to support large files in ext4 The follow up patch with convert the ext4_inode i_blocks to represent the number of blocks in file system block size. This changes makes it possible to have a block number 2**32 -1 which will result in overflow if the block number is represented by signed long. This patch convert all the block number to type ext4_lblk_t which is typedef to __u32 Also remove dead code ext4_ext_walk_space Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: Eric Sandeen <sandeen@redhat.com>
