Description

### Description

Currently, MS_REMOUNT sets mount-specific options (noexec, noatime, nodev, nosuid, ro/rw), but does not pass the updated `data` to the underlying filesystem to be reconfigured.

This also affects the new mount API, blocking a proper implementation of FSCONFIG_CMD_RECONFIGURE.
