The initial implementation for this was provided by kaetemi, originally as a mount flag. However, it has been modified here to be self-contained in an explicit runtime function that can be called after mount. The reasons for an explicit function: 1. lfs_mount stays a strictly readonly operation, and avoids pulling in all of the write machinery. 2. filesystem-wide operations such as lfs_fs_grow can be a bit risky, and irreversable. The action of growing the filesystem should be very intentional. --- One concern with this change is that this will be the first function that changes metadata in the superblock. This might break tools that expect the first valid superblock entry to contain the most recent metadata, since only the last superblock in the superblock chain will contain the updated metadata.
