Subject: [PATCH 029/217] ndctl/namespace: Suppress -ENXIO when processing all
namespaces.
When processing all namespaces and no namespaces exist user gets the
default -ENXIO. Set default rc to 0 when processing all namespaces.
This avoids confusing error message printed in addition to the message
saying 0 namespaces were affected.
Before:
# ndctl check-namespace all
namespace0.0: namespace_check: namespace0.0: check aborted, namespace online
error checking namespaces: Device or resource busy
checked 0 namespaces
# ndctl disable-namespace all
disabled 1 namespace
# ndctl check-namespace all
namespace0.0: namespace_check: Unable to recover any BTT info blocks
error checking namespaces: No such device or address
checked 0 namespaces
# ndctl destroy-namespace all
destroyed 1 namespace
# ndctl check-namespace all
error checking namespaces: No such device or address
checked 0 namespaces
# ndctl destroy-namespace all
error destroying namespaces: No such device or address
destroyed 0 namespaces
After:
# ndctl check-namespace all
namespace0.0: namespace_check: namespace0.0: check aborted, namespace online
error checking namespaces: Device or resource busy
checked 0 namespaces
# ndctl disable-namespace namespace0.0
disabled 1 namespace
# ndctl check-namespace all
namespace0.0: namespace_check: Unable to recover any BTT info blocks
error checking namespaces: No such device or address
checked 0 namespaces
# ndctl destroy-namespace all
destroyed 1 namespace
# ndctl check-namespace all
checked 0 namespaces
# ndctl destroy-namespace all
destroyed 0 namespaces
# ndctl destroy-namespace all
destroyed 0 namespaces
Note: this does change the return value from -ENXIO to 0 in the cases
when no namespaces exist and processing all namespaces was requested.
