Crate rsext4 

Core ext4 filesystem implementation.

This crate contains the main filesystem domains:

• Filesystem mount, sync, and mkfs (api, ext4)
• Block device and journal integration (blockdev, loopfile, jbd2)
• Block groups, bitmaps, and caches (blockgroup_description, bitmap, cache)
• File and directory operations (file, dir, entries)
• Disk metadata structures (disknode, superblock)
• Supporting configuration and utilities (config, endian, tool)
