The branch main has been updated by jrtc27: URL: https://cgit.FreeBSD.org/src/commit/?id=f6ee1d20d36813e9906916f48cf06f44a2fd668d commit f6ee1d20d36813e9906916f48cf06f44a2fd668d Author: Jessica Clarke <jrtc27@FreeBSD.org> AuthorDate: 2026-07-13 03:03:03 +0000 Commit: Jessica Clarke <jrtc27@FreeBSD.org> CommitDate: 2026-07-13 03:03:03 +0000 kern_thread: Fix i386 p_emuldata KBI assertion On amd64 there was 4 bytes of padding between the 20-byte p_comm and (for LP64) 8-byte p_sysent, so the addition of p_execblock just caused that padding to be eaten up. However, on i386, there was no such padding, and so the addition of p_execblock rippled through to p_emuldata.
