Since commit 565a4147d17a ("fs: btrfs: Add more checksum algorithms") btrfs uses the sha256 checksum algorithm. But Kconfig lacks to select it. This leads to compilation errors: fs/built-in.o: In function `hash_sha256': fs/btrfs/crypto/hash.c:25: undefined reference to `sha256_starts' fs/btrfs/crypto/hash.c:26: undefined reference to `sha256_update' fs/btrfs/crypto/hash.c:27: undefined reference to `sha256_finish'
