See recent commit "qapi: Relax doc string @name: description
indentation rules" for rationale.
Reflow paragraphs to 70 columns width, and consistently use two spaces
to separate sentences.
To check the generated documentation does not change, I compared the
generated HTML before and after this commit with "wdiff -3". Finds no
differences. Comparing with diff is not useful, as the reflown
paragraphs are visible there.

|
|
# A yank instance can be yanked with the @yank qmp command to recover
|
|
# from a hanging QEMU.
|
|
#
|
|
# Currently implemented yank instances:
|
|
#
|
|
# - nbd block device: Yanking it will shut down the connection to the
|
|
# nbd server without attempting to reconnect.
|
|
# - socket chardev: Yanking it will shut down the connected socket.
|
|
# - migration: Yanking it will shut down all migration connections.
|
|
# Unlike @migrate_cancel, it will not notify the migration process,
|
|
# so migration will go into @failed state, instead of @cancelled
|
|
# state. @yank should be used to recover from hangs.
