Can't change mount_point owner

when i use bfs_mount to mount the bfs in a directory success ,but when i chown the directory ,the command do nothing, so just the mount user can access the diretory, other user shows permission denied. How can i fix the problem? tks

The issue names no files, tests, or entry points beyond bfs_mount. Start by reproducing the mount, chown, and permission-denied sequence, then trace how mount-point ownership is handled. Done means ownership changes are honored for access by other users, with a regression test covering the reported sequence.
