Getting disk version..

[bitzer-tjo]

Hi

When we update to the latest LFS version, it may use a filesystem created with the privious version.
So I would like, after mount, get the disk version of the mounted filesystem and than call the makeconsisten function to change the disk version of it..

Am I mistaken or is there no function to get disk version of the underlaying filesystem?

Hi @TjoBitDk, thanks for creating an issue.

The intention was that lfs_fs_mkconsistent could be called unconditionally, it does no work if the filesystem is already consistent/version bumped. Also note lfs_fs_mkconsistent is called implicitly by all write operations. You don't need to call it yourself unless you want to force littlefs to write the minor version bump.

But I can see how accessing the current minor version would be handy. We can add this.

The first place that comes to mind is lfs_fs_stat in #753, though that PR is stalled, so maybe we should bring in lfs_fs_stat in a separate PR.

Functionality for this is being added in #838
