Damien George 2acc087880 extmod/vfs_lfs: Add mtime support to littlefs files. ... This commit adds support for modification time of files on littlefs v2 filesystems, using file attributes. For some background see issue #6114. Features/properties of this implementation: - Only supported on littlefs2 (not littlefs1). - Uses littlefs2's general file attributes to store the timestamp. - The timestamp is 64-bits and stores nanoseconds since 1970/1/1 (if the range to the year 2554 is not enough then additional bits can be added to this timestamp by adding another file attribute). - mtime is enabled by default but can be disabled in the constructor, eg: uos.mount(uos.VfsLfs2(bdev, mtime=False), '/flash') - It's fully backwards compatible, existing littlefs2 filesystems will work without reformatting and timestamps will be added transparently to existing files (once they are opened for writing). - Files without timestamps will open correctly, and stat will just return 0 for their timestamp. - mtime can be disabled or enabled each mount time and timestamps will only be updated if mtime is enabled (otherwise they will be untouched).
