I understand that, but the FUSE low-level API doesn't use vnodes to identify files, it uses the inode number. So when a program calls fstat() it generates a GETATTR event in FUSE that must be handled by a function with this prototype: -- int zfsfuse_getattr(fuse_req_t req, fuse_ino_t ino, struct fuse_file_info *fi); -- So the file is identified by the "ino" parameter (the inode number). If you're wondering what the "fi" parameter is for - in this handler it's reserved for future use and is always NULL. So in order to get the associated vnode I must call zfs_zget() first, at the top of almost every FUSE handler: ... vfs_t *vfs = (vfs_t *) fuse_req_userdata(req); zfsvfs_t *zfsvfs = vfs->vfs_data; ZFS_ENTER(zfsvfs); znode_t *znode; int error = zfs_zget(zfsvfs, ino, &znode, B_TRUE); ... The problem is that zfs_zget() will return ENOENT if the inode has been unlinked, so that's why I had to add that boolean parameter.
