The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=02a226ac342f0fb622e654e461c41f4f588f4186 commit 02a226ac342f0fb622e654e461c41f4f588f4186 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2022-07-27 19:00:22 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2022-07-27 19:13:58 +0000 Suppress possible unused variable warning for icl_soft.c With clang 15, the following -Werror warning is produced on i386: sys/dev/iscsi//icl_soft.c:1277:6: error: variable 'i' set but not used [-Werror,-Wunused-but-set-variable] int i; ^ The 'i' variable is used later in the icl_soft_conn_pdu_get_bio() function, via the PHYS_TO_DMAP() macro. However, on i386 and some other architectures, this macro is defined to panic immediately, so in those cases, 'i' is indeed not used. Suppress the warning by marking 'i' as unused.
