The branch stable/13 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=7b9e74754674be7afa1059f4ca66d6c6723efdc9 commit 7b9e74754674be7afa1059f4ca66d6c6723efdc9 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-12-05 00:27:22 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2023-05-03 00:03:01 +0000 libsa: Disable -Wdangling-pointer for zfs.c. GCC 12 warns about a dangling pointer to 'objid' in zfs_bootenv_initial(). However, this appears to be a false positive as the pointer to 'objid' is only passed to zfs_lookup_dataset() but not saved anywhere that outlives the lifetime of the zfs_bootenv_initial() function.
