v2.7
This is a small release to add some features that help with the previous on-disk minor-version bump, per feedback from @rojer, @TjoBitDk, and others.
What's new?
-
Added
lfs_fs_statas an analog for the POSIX stavfs (#838)This now provides access to the on-disk format-time configuration:
disk_version- on-disk versionname_max- configurable name limitfile_max- configurable name limitattr_max- configurable name limit
And may be extended in the future. Notably, the current block avail/usage is missing due to performance concerns, but can be retrieved with an explicit call to
lfs_fs_size. -
Added support for writing previous on-disk minor-versions (#839)
This feature is behind a compile-time flag, so in order to write lfs2.0 you need to compile with
LFS_MULTIVERSIONdefined.LFS_MULTIVERSIONenables an additional config option,disk_version, which currently supports three options:disk_version=0=> write the most recent littlefs versiondisk_version=0x00020001=> write lfs2.1disk_version=0x00020000=> write lfs2.0 (no FCRC)
