Remove the resize flag and use the same code path for all callers. This flag was added by commit 18f0316 to allow virStorageFileResize use 'safezero' while preserving the behavior. Explicitly return -2 when a fallback to a different method should be done, to make the code path more obvious. Fail immediately when ftruncate fails in the mmap method, as we did before commit 18f0316.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
