__ubsan_handle_divrem_overflow() incorrectly uses the RHS to report. It always reports the same log: division of -1 by -1. But it should report division of LHS by -1.

Pull crypto library fixes from Eric Biggers: "Fix a regression where 'make clean' stopped removing some of the generated assembly files on arm and arm64" * tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: lib/crypto: ensure generated *.S files are removed on make clean lib/crypto: sha: Update Kconfig help for SHA1 and SHA256

lib/crypto: ensure generated *.S files are removed on make clean

2025-08-15T01:01:03Z

make clean does not check the kernel config when removing files. As such, additions to clean-files under CONFIG_ARM or CONFIG_ARM64 are not evaluated. For example, when building on arm64, this means that lib/crypto/arm64/sha{256,512}-core.S are left over after make clean. Set clean-files unconditionally to ensure that make clean removes these files.

ref_tracker: use %p instead of %px in debugfs dentry name

As Kees points out, this is a kernel address leak, and debugging is not a sufficiently good reason to expose the real kernel address.

lib/sbitmap: convert shallow_depth from one word to the whole sbitmap

2025-08-07T12:30:17Z

Currently elevators will record internal 'async_depth' to throttle asynchronous requests, and they both calculate shallow_dpeth based on sb->shift, with the respect that sb->shift is the available tags in one word. However, sb->shift is not the availbale tags in the last word, see __map_depth: if (index == sb->map_nr - 1) return sb->depth - (index << sb->shift); For consequence, if the last word is used, more tags can be get than expected, for example, assume nr_requests=256 and there are four words, in the worst case if user set nr_requests=32, then the first word is the last word, and still use bits per word, which is 64, to calculate async_depth is wrong. One the ohter hand, due to cgroup qos, bfq can allow only one request to be allocated, and set shallow_dpeth=1 will still allow the number of words request to be allocated. Fix this problems by using shallow_depth to the whole sbitmap instead of per word, also change kyber, mq-deadline and bfq to follow this, a new helper __map_depth_with_shallow() is introduced to calculate available bits in each word.
