ext4: Add inode version support in ext4
This patch adds 64-bit inode version support to ext4. The lower 32 bits are stored in the osd1.linux1.l_i_version field while the high 32 bits are stored in the i_version_hi field newly created in the ext4_inode. This field is incremented in case the ext4_inode is large enough. A i_version mount option has been added to enable the feature.
