From d55215c50e4eaa4b906a42ef45884d8fcbadc777 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 3 Jun 2016 12:10:37 -0700 Subject: [PATCH] IB/hfi1: Use bit 0 instead of bit 1 The first argument of test_bit() and clear_bit() is a bit number and not a bitmask. Hence change that first argument from (1 << 0) into 0. This patch avoids that smatch reports the following warnings: user_sdma.c:1059: sdma_cache_evict() warn: test_bit() takes a bit number user_sdma.c:1590: sdma_rb_remove() warn: test_bit() takes a bit number Signed-off-by: Bart Van Assche Cc: Mike Marciniszyn Cc: Dennis Dalessandro Signed-off-by: Doug Ledford --- drivers/infiniband/hw/hfi1/user_sdma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/infiniband/hw/hfi1/user_sdma.c b/drivers/infiniband/hw/hfi1/user_sdma.c index 29f4795f866c..2eca5b7394a2 100644 --- a/drivers/infiniband/hw/hfi1/user_sdma.c +++ b/drivers/infiniband/hw/hfi1/user_sdma.c @@ -183,7 +183,7 @@ struct user_sdma_iovec { struct sdma_mmu_node *node; }; -#define SDMA_CACHE_NODE_EVICT BIT(0) +#define SDMA_CACHE_NODE_EVICT 0 struct sdma_mmu_node { struct mmu_rb_node rb; -- 2.39.5
