[GIT PULL] configfs for v6.16
From: Andreas Hindborg
Date: Fri May 16 2025 - 03:52:23 EST
Hi Linus,
This is my first pull request after picking up configfs [1], and my
first pull request to you. I hope I got everything right!
Summary
=======
This pull request contains configfs changes for v6.16:
- 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.
