Cover letter [Cluster-devel] [DLM PATCH 0/6] Misc DLM Improvements Regarding Socket Errors
Quoted 4 lines · Bob Peterson

I've been doing a bunch of recovery testing with DLM and discovered some issues. This collection of 6 patches addresses those issues. Some of them are of my own making, introduced by the recent patches that made DLM print socket connection errors, and recovery from those errors.

Thanks Bob, perhaps I've not been paying close enough attention, but it's unclear to me how this patch set relates the the most accute issue we have at the moment, which are the problems introduced here:

Subject: [PATCH] dlm: print error from kernel_sendpage

Print a dlm-specific error when a socket error occurs when sending a dlm message.

Could we begin with one patch that's easy to track that directly resolves the issues with that commit (perhaps even a revert if it's not simple to fix directly)? That brings us back to a known-good place, from which we can look at cleanups and changes.
