-/** @file
- *
- * This example implements a file system with two files:
- *   * 'current-time', whose contents change dynamically:
- *     it always contains the current time (same as in
- *     notify_inval_inode.c).
- *   * 'growing', whose size changes dynamically, growing
- *     by 1 byte after each update. This aims to check
- *     if cached file metadata is also invalidated.
- *
- * ## Compilation ##
- *
- *     gcc -Wall @file `pkg-config fuse3 --cflags --libs` -o invalidate_path
- *
- * ## Source code ##
- * \include @file
