The change I made only affects compat syscalls.  I didn't touch any
logic inside any file systems.

If there is a problem in the file system and the compat syscall would
have panicked, then a native syscall would simply return garbage to
the user.  My change doesn't affect this.

(Not garbage in the sense of uninitialized memory necessarily, but
whatever garbage some file system bug or corrupted disk yielded.)
