[Qemu-devel] [PATCH v7 for 2.1 0/4] Allow custom backing-file string in commit/stream

[Jeff Cody <jcody@redhat.com>]

This is part 2 of a split of "Modify block jobs to use node-names".

These patches add a helper function, allow block-commit and block-stream to 
change backing files, and adds a standalone API to change backing files.

The api to change backing files relies still on the "check active layer blocker"
workaround on blockers.

Jeff Cody (4):
  block: add helper function to determine if a BDS is in a chain
  block: extend block-commit to accept a string for the backing file
  block: add backing-file option to block-stream
  block: add QAPI command to allow live backing file change
