[libvirt] [PATCH 0/7] Adjustments for storage/qemu volume/file backing size settings

[John Ferlan]

A bit of a mix between fixing some bugs and merging some code between
the block info/stats fetching of backing store data and storage backend
data for volume allocation, capacity, and physical sizes.

Patch 1 just adjusts some comments

Patches 2-3 are code motion

Patch 4 alters how domain/qemu will open the backing store from an open
to a qemuFileOpen and it allows for fetching of more physical sizes (the
code only gets the block backing stores now)

Patch 5 shares the setting of the various size values between storage driver
and domain/qemu

Patch 6 shares the recalculation of the capacity value (it may not be necessary
for patch 5, but I left it there since there's multiple other paths to the
VolTargetInfoFD API).

Patch 7 fixes an issue with displaying the allocation value of a qcow2 backed
file for the GetBlockInfo API (the results will match volume code now).


John Ferlan (7):
  qemu: Clean up description for qemuStorageLimitsRefresh
  qemu: Add helpers to handle stat data for qemuStorageLimitsRefresh
  qemu: Introduce helper qemuDomainStorageUpdatePhysical
  util: Introduce virStorageSourceUpdatePhysicalSize
  util: Introduce virStorageSourceUpdateBackingSizes
  util: Introduce virStorageSourceUpdateCapacity
  qemu: Fix GetBlockInfo setting allocation from wr_highest_offset
