[PATCH] PCI: Test for bit underflow in pcie_set_readrq()

After commit cbc654d18d37 ("bitops: Add __attribute_const__ to generic ffs()-family implementations"), which allows GCC's value range tracker to see past ffs(), GCC 8 on ARM thinks that it might be possible that "ffs(rq) - 8" used here: v = FIELD_PREP(PCI_EXP_DEVCTL_READRQ, ffs(rq) - 8);

[PATCH v15 2/5] rust: add bindings for bitops.h

Makes atomic set_bit and clear_bit inline functions as well as the non-atomic variants __set_bit and __clear_bit available to Rust. Adds a new MAINTAINERS section BITOPS API BINDINGS [RUST]. Suggested-by: Alice Ryhl Suggested-by: Yury Norov Signed-off-by: Burak Emir Reviewed-by: Alice Ryhl Ack

[PATCH v15 3/5] rust: add bitmap API.

Provides an abstraction for C bitmap API and bitops operations. This commit enables a Rust implementation of an Android Binder data structure from commit 15d9da3f818c ("binder: use bitmap for faster descriptor lookup"), which can be found in drivers/android/dbitmap.h. It is a step towards upstream

[PATCH v15 1/5] rust: add bindings for bitmap.h

[PATCH v15 5/5] rust: add dynamic ID pool abstraction for bitmap

This is a port of the Binder data structure introduced in commit 15d9da3f818c ("binder: use bitmap for faster descriptor lookup") to Rust. Like drivers/android/dbitmap.h, the ID pool abstraction lets clients acquire and release IDs. The implementation uses a bitmap to know what IDs are in use, and

[PATCH v15 4/5] rust: add find_bit_benchmark_rust module.

Microbenchmark protected by a config FIND_BIT_BENCHMARK_RUST, following `find_bit_benchmark.c` but testing the Rust Bitmap API. We add a fill_random() method protected by the config in order to maintain the abstraction. The sample output from the benchmark, both C and Rust version: find_bit_benc

[PATCH v15 0/5] rust: adds Bitmap API, ID pool and bindings

This series adds a Rust bitmap API for porting the approach from commit 15d9da3f818c ("binder: use bitmap for faster descriptor lookup") to Rust. The functionality in dbitmap.h makes use of bitmap and bitops. The Rust bitmap API provides a safe abstraction to underlying bitmap and bitops operation
