The branch main has been updated by kib: URL: https://cgit.FreeBSD.org/src/commit/?id=3b5331dd8d413807cf1d6cb26630ccf9028168e6 commit 3b5331dd8d413807cf1d6cb26630ccf9028168e6 Author: Konstantin Belousov <kib@FreeBSD.org> AuthorDate: 2021-10-21 17:46:36 +0000 Commit: Konstantin Belousov <kib@FreeBSD.org> CommitDate: 2021-10-21 18:40:46 +0000 uipc_shm: silent warnings about write-only variables in largepage code In shm_largepage_phys_populate(), the result from vm_page_grab() is only needed for assertion. In shm_dotruncate_largepage(), there is a commented-out prototype code for managed largepages. The oldobjsz is saved for its sake, so mark the variable as __unused directly.
