This refactor unifies setup of data for disk hotplug and command line
generation.
This applies on top of
'qemu: Handle managed persisten reservations separately'
as that applies on top of the staging branch for my ACKed refactors
which moved now, you can fetch everything at:
git fetch git://pipo.sk/pipo/libvirt.git disk-hotplug-refactor
Peter Krempa (9):
qemu: hotplug: Remove qemuDomainDelDiskSrcTLSObject
qemu: alias: Rename qemuAliasFromDisk to qemuAliasDiskDriveFromDisk
qemu: Reuse qemuBlockStorageSourceAttachApply in disk hotplug
qemu: hotplug: Extract hotplug of PR into
qemuBlockStorageSourceAttachApply
qemu: hotplug: Extract hotplug of secrets into
qemuBlockStorageSourceAttachApply
qemu: hotplug: Extract hotplug of TLS into
qemuBlockStorageSourceAttachApply
qemu: command: Rename qemuBuildDiskDriveCommandLine
qemu: command: Extract setup of one disk's command line
qemu: command: Refactor disk commandline formatting

New subject: [libvirt] [PATCH 3/9] qemu: Reuse qemuBlockStorageSourceAttachApply in disk hotplug
Create a new "Prepare" function and move the drive add code into the new
helpers. This will eventually allow to simplify and unify the attaching
code for use with blockdev at the same time as providing compatibility
with older qemus.

Even though this call is unrelated to the other two, shouldn't rollback
be in reverse order?

I'll put it so that it's strictly in reverse order, but I made it
impossible to create the data structure in a way that would allow

New subject: [libvirt] [PATCH 9/9] qemu: command: Refactor disk commandline formatting
Now that we have one place that sets up all disk-related objects to
qemuBlockStorageSourceAttachDataPtr we can easily reuse the data in the
command-line formatter by implementing a worker which will convert the
data.
A huge advantage is that it will be way easier to integrate this with
-blockdev later on.
