Expose fuse_config.use_ino as useIno, with the native spelling use_ino as an alias. With it set, the ino returned by getattr is reported as st_ino; without it libfuse substitutes its own node ids, so two hard links to one file stat as different inodes. FUSE 3 moved use_ino from the mount options into struct fuse_config, and fuse_new() rejects it on the command line, so it travels as a new operation flag that the init hook applies, the same way directIo does.

Summary
Adds a
useInooption (aliasuse_ino) that setsfuse_config.use_ino, so theinoreturned bygetattris reported asst_ino. Without it libfuse substitutes its own node ids, and two hard links to one file stat as different inodes.Related to #16 and #17
fuse_config.use_inoIn FUSE 3,
use_inois afuse_configfield andfuse_new()rejects it as a mount option. It's therefore passed as an operation flag and applied in the init hook, the same waydirectIois.Compatibility
New opt-in boolean; nothing changes when it's omitted. Linux and macFUSE.
