If anyone has any objections, please let me know. ------------------ From: Bart Van Assche commit db7489e07669073970358b6cacf6a9dd8dc9275e upstream. Move the __attribute_const__ declarations such that sparse understands that these apply to the function itself and not to the return type. This avoids that sparse reports error messages like the following: drivers/infiniband/core/verbs.c:73:12: error: symbol 'ib_event_msg' redeclared with different type (originally declared at include/rdma/ib_verbs.h:470) - different modifiers Fixes: 2b1b5b601230 ("IB/core, cma: Nice log-friendly string helpers") Signed-off-by: Bart Van Assche Cc: Sagi Grimberg Reviewed-by: Sagi Grimberg Signed-off-by: Doug Ledford Signed-off-by: Kamal Mostafa --- drivers/infiniband/core/cma.c | 2 +- drivers/infiniband/core/verbs.c | 4 ++-- include/rdma/ib_verbs.h | 4 ++-- include/rdma/rdma_cm.h | 2 +- 4 files changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/infiniband/core/cma.c b/drivers/infiniband/core/cma.c index 143ded2..a7c1788 100644 --- a/drivers/infiniband/core/cma.c +++ b/drivers/infiniband/core/cma.c @@ -84,7 +84,7 @@ static const char * const cma_events[] = { [RDMA_CM_EVENT_TIMEWAIT_EXIT] = "timewait exit", }; -const char *rdma_event_msg(enum rdma_cm_event_type event) +const char *__attribute_const__ rdma_event_msg(enum rdma_cm_event_type event) { size_t index = event; diff --git a/drivers/infiniband/core/verbs.c b/drivers/infiniband/core/verbs.c index bac3fb4..a162f65 100644 --- a/drivers/infiniband/core/verbs.c +++ b/drivers/infiniband/core/verbs.c @@ -70,7 +70,7 @@ static const char * const ib_events[] = { [IB_EVENT_GID_CHANGE] = "GID changed", }; -const char *ib_event_msg(enum ib_event_type event) +const char *__attribute_const__ ib_event_msg(enum ib_event_type event) { size_t index = event; @@ -104,7 +104,7 @@ static const char * const wc_statuses[] = { [IB_WC_GENERAL_ERR] = "general error", }; -const char *ib_wc_status_msg(enum ib_wc_status status) +const char *__attribute_const__ ib_wc_status_msg(enum ib_wc_status status) { size_t index = status; diff --git a/include/rdma/ib_verbs.h b/include/rdma/ib_verbs.h index b0f898e..8ee1a4b 100644 --- a/include/rdma/ib_verbs.h +++ b/include/rdma/ib_verbs.h @@ -467,7 +467,7 @@ enum ib_event_type { IB_EVENT_GID_CHANGE, }; -__attribute_const__ const char *ib_event_msg(enum ib_event_type event); +const char *__attribute_const__ ib_event_msg(enum ib_event_type event); struct ib_event { struct ib_device *device; @@ -720,7 +720,7 @@ enum ib_wc_status { IB_WC_GENERAL_ERR }; -__attribute_const__ const char *ib_wc_status_msg(enum ib_wc_status status); +const char *__attribute_const__ ib_wc_status_msg(enum ib_wc_status status); enum ib_wc_opcode { IB_WC_SEND, diff --git a/include/rdma/rdma_cm.h b/include/rdma/rdma_cm.h index c92522c..31afb5c 100644 --- a/include/rdma/rdma_cm.h +++ b/include/rdma/rdma_cm.h @@ -62,7 +62,7 @@ enum rdma_cm_event_type { RDMA_CM_EVENT_TIMEWAIT_EXIT }; -__attribute_const__ const char *rdma_event_msg(enum rdma_cm_event_type event); +const char *__attribute_const__ rdma_event_msg(enum rdma_cm_event_type event); enum rdma_port_space { RDMA_PS_SDP = 0x0001, -- 1.9.1
