[v2,0/5] target: improve Data-Out and NOP timeout error reporting

Message

David Disseldorp Oct. 12, 2018, 10:01 a.m. UTC

The following patchset converts existing Data-Out and NOP ping timeout
messages from pr_debug() to pr_error(), to reflect the seriousness of
unexpected connection termination events.

These events can be triggered using a couple of libiscsi client hacks:

https://github.com/ddiss/libiscsi/tree/hack-lio-trigger-nop-timeout

Cheers, David
