[pbs-devel] [PATCH RFC proxmox/proxmox-backup] restore files from pxar sparsely

[Dominik Csapak]

to be able to restore containers with big sparse files

ideally(?) we would save hole information directly in the pxar archive
and not even use zero chunks, so that we can have smaller
pxar archives, and accurately restore sparse files like they were before

for now, restore all files sparsely

proxmox:

Dominik Csapak (2):
  add tools/zero: add fast zero comparison code
  proxmox: add sparse_copy(_async) to tools::io
