Subject: [PATCH 0/3] Remove the usage of Rust native atomics in debugfs
Date: Tue, 21 Oct 2025 23:53:21 -0400 [thread overview]
Message-ID: <20251022035324.70785-1-boqun.feng@gmail.com> (raw)
Rust native atomics are not supposed to be used in kernel due to the
mismatch of memory model, since we now have the LKMM atomics in Rust,
remove the usage of Rust native atomics in debugfs.
(help is appreciated if anyone wants to help in other subsystem)
