We can add a device aliasing file which can map the whole device with an
extent, not using node blocks. This mapped area should be pinned and
normally used for read-only usages. After finished using it, we can
deallocate the whole area and return it back to use it for other files.

Previously, once fsck.f2fs detects that directory missed '.' or

This patch abandons previous implementation, and do repaires directly.

This patch introduces a new tool inject.f2fs to modify metadata or data
(directory entry) of f2fs image offline flexibly.
With inject.f2fs, it is easier to generate a corrupted f2fs image, which
can help verify fsck or reproduce userspace behaviors of some a fault.
If option `--dry-run' is used, nothing really gets changed, and that
could be used to get the value of a specified field.
The following patches enable injecting each part of f2fs.
