Pull configfs updates from Andreas Hindborg:
- Allow creation of rw files with custom permissions. This allows
drivers to better protect secrets written through configfs
- Fix a bug where an error condition did not cause an early return
while populating attributes
- Report ENOMEM rather than EFAULT when kvasprintf() fails in
config_item_set_name()
- Add a Rust API for configfs. This allows Rust drivers to use configfs
through a memory safe interface
