kernel/linux.git/lib/crypto/mpi/longlong.h, branch v7.1Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v7.12026-03-23T17:33:51+00:00lib: crypto: fix comments for count_leading_zeros()2026-03-23T17:33:51+00:00Yury Norovynorov@nvidia.com2026-03-10T20:53:02+00:00urn:sha1:18c48899653fa7a04120537c228031b5c7e4e9d6
count_leading_zeros() is based on fls(), which is defined for x == 0,
contrary to __ffs() family. The comment in crypto/mpi erroneously
states that the function may return undef in such case.
Fix the comment together with the outdated function signature, and now
that COUNT_LEADING_ZEROS_0 is not referenced in the codebase, get rid of
it too.

crypto: lib - Move mpi into lib/crypto2023-08-11T11:19:27+00:00Herbert Xuherbert@gondor.apana.org.au2023-08-04T09:24:34+00:00urn:sha1:2a598d0b2800aa23ba51adcf060cec524aaa63b2
As lib/mpi is mostly used by crypto code, move it under lib/crypto
so that patches touching it get directed to the right mailing list.
