Libvirt native C API and daemons
18f03166fd
Currently virStorageFileResize() function uses build conditionals to choose either the posix_fallocate() or syscall(SYS_fallocate) with no fallback in order to preallocate the space in the newly resized file. Since the safezero code has a similar set of conditionals modify the resize and safezero code in order to allow the resize logic to make use of safezero to unify the look/feel of the code paths. Add a new boolean (resize) to safezero() to make the optional decision whether to try syscall(SYS_fallocate) if the posix_fallocate fails because HAVE_POSIX_FALLOCATE is not defined (eg, return -1 and errno == 0). Create a local safezero_sys_fallocate in order to handle the resize code paths that support that. If not present, the set errno = ENOSYS in order to allow the caller to handle the failure scenarios.

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.
