Hi all, After merging the block tree, today's linux-next build (arm multi_v7_defconfig) failed like this: net/sunrpc/xprtsock.c: In function 'xs_flush_bvec': net/sunrpc/xprtsock.c:390:2: error: implicit declaration of function 'for_each_bvec'; did you mean 'for_each_net'? [-Werror=implicit-function-declaration] for_each_bvec(bv, bvec, bi, bi) ^~~~~~~~~~~~~ for_each_net net/sunrpc/xprtsock.c:390:33: error: expected ';' before 'flush_dcache_page' for_each_bvec(bv, bvec, bi, bi) ^ ; flush_dcache_page(bv.bv_page); ~~~~~~~~~~~~~~~~~ Caused by commit f3effe4c1240 ("block: rename bvec helpers") interacting with commit 6a829eb8619f ("SUNRPC: Fix TCP receive code on archs with flush_dcache_page()") from the nfs-anna tree. [I love API changes :-(] I have applied the following merge fix patch: From: Stephen Rothwell Date: Wed, 16 Jan 2019 13:32:59 +1100 Subject: [PATCH] SUNRPC: merge fix for "block: rename bvec helpers" Signed-off-by: Stephen Rothwell --- net/sunrpc/xprtsock.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/sunrpc/xprtsock.c b/net/sunrpc/xprtsock.c index 7754aa3e434f..47f29cc23f27 100644 --- a/net/sunrpc/xprtsock.c +++ b/net/sunrpc/xprtsock.c @@ -387,7 +387,7 @@ xs_flush_bvec(const struct bio_vec *bvec, size_t count, size_t seek) struct bio_vec bv; bvec_iter_advance(bvec, &bi, seek & PAGE_MASK); - for_each_bvec(bv, bvec, bi, bi) + for_each_segment(bv, bvec, bi, bi) flush_dcache_page(bv.bv_page); } #else -- 2.20.1 -- Cheers, Stephen Rothwell
