[PATCH v2 0/4] enhance the path resolution capability in fs_parser

[Hongbo Li <lihongbo22@huawei.com>]

Mount options with path should be parsed into block device or inode. As
the new mount API provides a serial of parsers, path should also be 
looked up into block device within these parsers, not in each specific
filesystem.

The following is a brief overview of the patches, see the patches for
more details.

Patch 1-2: Enhance the path resolution capability in fs_parser.
Patch 3: Fix the `journal_path` options error in ext4. 
Patch 4: Remove the `fs_lookup_param` and its description.

Comments and questions are, as always, welcome.

Thanks,
Hongbo
