[Qemu-devel] [PATCH 0/3] nbd-client: drop extra error noise

[Vladimir Sementsov-Ogievskiy]

Hi all.

It was discussed, that error messages, produced by error_reprt_err's,
added in f140e300 are
1. not really needed
2. subject to race conditions

And it was decided to drop them (switch to trace-points), look thread
https://lists.gnu.org/archive/html/qemu-devel/2018-08/msg00833.html

So, I've also dropped error_report_err, added earlier in be41c100c0d
and later in 78a33ab5878.

Hmm, I've tried to run 83 iotest in a loop, and it didn't fail, even
before these patches.

  error: add error_get_hint
  nbd: publish _lookup functions
  block/nbd-client: use traces instead of noisy error_report_err
