Subject: [GIT PULL] vfs rust file

Hey Linus,

/* Summary */

This contains the file abstractions needed by the Rust implementation of
the Binder driver and other parts of the kernel.

Let's treat this as a first attempt at getting something working but I
do expect the actual interfaces to change significantly over time.
Simply because we are still figuring out what actually works. But
there's no point in further theorizing. Let's see how it holds up with
actual users.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

All patches are based on v6.12-rc2 and have been sitting in linux-next.
No build failures or warnings were observed.

/* Conflicts */
