[pbs-devel] [PATCH v2 proxmox-backup 5/5] backup: touch all chunks, even if they exist

We need to update the atime of chunk files if they already exist,
otherwise a concurrently running GC could sweep them away.
This is protected with ChunkStore.mutex, so the fstat/unlink does not
race with touching.
