DropGuard runs a FnOnce callback when dropped and provides dismiss() to take ownership of the wrapped value without running the cleanup callback. Changes since v2: - Clarified why DropGuard is added alongside the existing ScopeGuard. - Fixed the core imports in mem.rs to follow the Rust kernel import style. The series was previously tested with: - make LLVM=1 rustfmtcheck - make LLVM=1 rustdoc - make LLVM=1 -j$(nproc) - git diff --check - scripts/checkpatch.pl The changes in v3 are limited to the import style and commit-message clarification.
