Subject: [PATCH 1/1] RDMA/rxe: Fix missing kconfig dependency on CRYPTO
Git-commit: 475f23b8c66d2892ad6acbf90ed757cafab13de7
Patch-mainline: v5.12
References: git-fixes
When RDMA_RXE is enabled and CRYPTO is disabled, Kbuild gives the
following warning:
WARNING: unmet direct dependencies detected for CRYPTO_CRC32
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- RDMA_RXE [=y] && (INFINIBAND_USER_ACCESS [=y] || !INFINIBAND_USER_ACCESS [=y]) && INET [=y] && PCI [=y] && INFINIBAND [=y] && INFINIBAND_VIRT_DMA [=y]
This is because RDMA_RXE selects CRYPTO_CRC32, without depending on or
selecting CRYPTO, despite that config option being subordinate to CRYPTO.
Fixes: cee2688e3cd6 ("IB/rxe: Offload CRC calculation when possible")
