Kyle Evans pointed out the same issue to me and I fixed it back in January 2024. Here is the commit https://sourceware.org/git/?p=3Dvalgrind.git;a=3Dcommit;h=3Dd0c17b5431e5448= c73f99322afb5aac442c2ee70 Other than painstakingly reading through the kernel source, is there any pl= ace where information about ioctls is gathered together (something like syscalls.master)? --=20 You are receiving this mail because: You are the assignee for the bug.=
