The branch stable/13 has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=fac45b6b9a58911a13c2709407863dbf8b7fd5b7 commit fac45b6b9a58911a13c2709407863dbf8b7fd5b7 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2024-04-21 03:04:04 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2024-04-25 03:59:20 +0000 ahc(4): resolve some minor nits In ahc_init(), qoutfifo is already assigned to effectively the same value a couple lines up, except in the first assignment it uses the proper definition; keep the more descriptive assignment. ahc_targetcmd_offset() gets the offset wrong entirely; as per the area of ahc_init() this diff also touches, targetcmds is laid out first in the shared map and it's followed by the qoutfifo. As a result, we'd generally be getting negative offsets here. We can't actually do a partial sync anyways, so there was no consequence to getting this wrong.
