This likely shouldn't be static inline, but an actual
function somewhere.
The return should probably be const char *.
Indexing a string array with an enum is generally unsafe.
I think it better to use a switch/case like:
const char *ptlrpc_import_state_name(enum lustre_imp_state state)
{
switch (state) {
case LUSTRE_IMP_CLOSED:
return "CLOSED";
case LUSTRE_IMP_NEW:
return "NEW";
case LUSTRE_IMP_DISCON:
return "DISCONN";
case LUSTRE_IMP_CONNECTING:
return "CONNECTING";
case LUSTRE_IMP_REPLAY:
return "REPLAY";
case LUSTRE_IMP_REPLAY_LOCKS:
return "REPLAY_LOCKS";
case LUSTRE_IMP_REPLAY_WAIT:
return "REPLAY_WAIT";
case LUSTRE_IMP_RECOVER:
return "RECOVER";
case LUSTRE_IMP_FULL:
return "FULL";
case LUSTRE_IMP_EVICTED:
return "EVICTED";
default:
return "UNKNOWN";
}
}
