From aef25338226660cdd4df908c2eff1abdcfca65e5 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 12 Feb 2016 17:01:11 -0800 Subject: libnvdimm, nfit: centralize command status translation The return value from an 'ndctl_fn' reports the command execution status, i.e. was the command properly formatted and was it successfully submitted to the bus provider. The new 'cmd_rc' parameter allows the bus provider to communicate command specific results, translated into common error codes. Convert the ARS commands to this scheme to: 1/ Consolidate status reporting 2/ Prepare for for expanding ars unit test cases 3/ Make the implementation more generic Cc: Vishal Verma Signed-off-by: Dan Williams --- drivers/nvdimm/bus.c | 2 +- drivers/nvdimm/dimm_devs.c | 6 +++--- 2 files changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers/nvdimm') diff --git a/drivers/nvdimm/bus.c b/drivers/nvdimm/bus.c index 5d28e9405f32..c3ba888e3e3a 100644 --- a/drivers/nvdimm/bus.c +++ b/drivers/nvdimm/bus.c @@ -587,7 +587,7 @@ static int __nd_ioctl(struct nvdimm_bus *nvdimm_bus, struct nvdimm *nvdimm, if (rc) goto out_unlock; - rc = nd_desc->ndctl(nd_desc, nvdimm, cmd, buf, buf_len); + rc = nd_desc->ndctl(nd_desc, nvdimm, cmd, buf, buf_len, NULL); if (rc < 0) goto out_unlock; if (copy_to_user(p, buf, buf_len)) diff --git a/drivers/nvdimm/dimm_devs.c b/drivers/nvdimm/dimm_devs.c index 651b8d19d324..c56f88217924 100644 --- a/drivers/nvdimm/dimm_devs.c +++ b/drivers/nvdimm/dimm_devs.c @@ -75,7 +75,7 @@ int nvdimm_init_nsarea(struct nvdimm_drvdata *ndd) memset(cmd, 0, sizeof(*cmd)); nd_desc = nvdimm_bus->nd_desc; return nd_desc->ndctl(nd_desc, to_nvdimm(ndd->dev), - ND_CMD_GET_CONFIG_SIZE, cmd, sizeof(*cmd)); + ND_CMD_GET_CONFIG_SIZE, cmd, sizeof(*cmd), NULL); } int nvdimm_init_config_data(struct nvdimm_drvdata *ndd) @@ -120,7 +120,7 @@ int nvdimm_init_config_data(struct nvdimm_drvdata *ndd) cmd->in_offset = offset; rc = nd_desc->ndctl(nd_desc, to_nvdimm(ndd->dev), ND_CMD_GET_CONFIG_DATA, cmd, - cmd->in_length + sizeof(*cmd)); + cmd->in_length + sizeof(*cmd), NULL); if (rc || cmd->status) { rc = -ENXIO; break; @@ -171,7 +171,7 @@ int nvdimm_set_config_data(struct nvdimm_drvdata *ndd, size_t offset, status = ((void *) cmd) + cmd_size - sizeof(u32); rc = nd_desc->ndctl(nd_desc, to_nvdimm(ndd->dev), - ND_CMD_SET_CONFIG_DATA, cmd, cmd_size); + ND_CMD_SET_CONFIG_DATA, cmd, cmd_size, NULL); if (rc || *status) { rc = rc ? rc : -ENXIO; break; -- cgit v1.2.3-59-g8ed1b
