Hi Herbert, After merging the crypto tree, today's linux-next build (x86_64 allmodconfig) produced this warning: In file included from drivers/crypto/chelsio/chcr_ipsec.c:66:0: drivers/crypto/chelsio/chcr_crypto.h:343:12: warning: 'chcr_ahash_continue' declared 'static' but never defined [-Wunused-function] static int chcr_ahash_continue(struct ahash_request *req); ^~~~~~~~~~~~~~~~~~~ Introduced by commit 5110e65536f3 ("crypto: chelsio -Split Hash requests for large scatter gather list") -- Cheers, Stephen Rothwell
