The branch main has been updated by kib: URL: https://cgit.FreeBSD.org/src/commit/?id=326836a1ebc6ce9b28c8f2bc1d177a444fba8ea6 commit 326836a1ebc6ce9b28c8f2bc1d177a444fba8ea6 Author: Konstantin Belousov <kib@FreeBSD.org> AuthorDate: 2023-11-18 09:23:22 +0000 Commit: Konstantin Belousov <kib@FreeBSD.org> CommitDate: 2023-11-28 17:32:53 +0000 nullfs: do not allow bypass on copy_file_range() There must be no callers of VOP_COPY_FILE_RANGE() except vn_copy_file_range(), which does enough to find the write-vnodes where to call the VOP.
