[Qemu-devel] [PATCH 00/19] nbd errors and traces refactoring

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

This is based on my "nbd: error path refactoring" series.

These series bring errp instead of LOG to the server too, making
some related refactorings.

nbd_negotiate_read and friends a dropped as was discussed in
"nbd: error path refactoring" thread.

finally - refactor traces to modern way too, to get rid of LOG()
macro at all.

Patches subgroup 01-x, where x <= 10 may be pushed as separate series,
as they are general enough.

11-14 needed to not create error-output on non-error disconnects in 15
16 is good addition for 15
17 is addition for 15 and in the same time prerequisite for 19

patches 18-19 may be pushed separately (but of course after 01-17 and
19 after 18)
