The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=0163de282e3195a1845f75b486adb3e1e7580199 commit 0163de282e3195a1845f75b486adb3e1e7580199 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-12-05 00:27:22 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2022-12-05 00:27:22 +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.
