Description
I encountered the same issue before. My previous solution was writing the whole struct to userspace instead of just one field. It would be nice to have an interface that could directly write a field to userspace. I will create an issue to track it.

Research direction
Start at litebox_shim_linux/src/syscalls/file.rs lines 1022-1036 and inspect RawMutPointer’s existing interface and the surrounding syscall handling. Define an interface for writing one struct field to userspace without writing the whole struct, then verify it against the cited case.
