The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=f4497b9f77795ece4d2f2fad4c0329d82d53bc63 commit f4497b9f77795ece4d2f2fad4c0329d82d53bc63 Author: Yuri <yuri@aetern.org> AuthorDate: 2022-06-27 15:48:31 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2022-06-27 17:06:31 +0000 smartpqi: Allocate DMA memory NOWAIT We're not allowed to wait in this allocation path, so allocate the memory NOWAIT instead of WAITOK. The code already copes with the failures that may result, so no additional code is needed.
