DropGuard runs a FnOnce callback when dropped and provides dismiss() to take ownership of the wrapped value without running the cleanup callback. Changes since v1: - Split the changes into separate patches for each affected module. - Added a separate KUnit configuration patch. The series was tested with: - make LLVM=1 rustfmtcheck - make LLVM=1 rustdoc - make LLVM=1 -j$(nproc) - git diff --check - scripts/checkpatch.pl Mohamed Osama (5): rust: add DropGuard KUnit test configuration rust: mem: add DropGuard rust: block: gen_disk: use DropGuard rust: serdev: use DropGuard rust: sync: lock: use DropGuard rust/kernel/Kconfig.test | 10 +++ rust/kernel/block/mq/gen_disk.rs | 11 +-- rust/kernel/mem.rs | 123 +++++++++++++++++++++++++++++++ rust/kernel/serdev.rs | 10 +-- rust/kernel/sync/lock.rs | 5 +- 5 files changed, 146 insertions(+), 13 deletions(-) -- 2.43.0
