Mitchell Horne 6f5141456e vtblk: secondary fix for dumping ... The code paths while dumping do not got through busdma. As such, safeguard against calling bus_dmamap_sync() with a NULL map. The x86 implementation tolerates this but others do not, resulting in a NULL dereference panic when dumping to a vtblk device on arm64, riscv, etc. Fixes: 782105f7c8 ("vtblk: Use busdma") Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D37990		2023-01-23 15:21:36 -04:00
