This gets rid of another stat() per volume, as well as cutting bytes read in half, when populating the volumes of a directory pool during a pool refresh. Not to mention that it provides an interface that can let gluster pools also probe file types. * src/util/virstoragefile.h (virStorageFileProbeFormatFromFD): Delete. (virStorageFileProbeFormatFromBuf): New prototype. (VIR_STORAGE_MAX_HEADER): New constant, based on... * src/util/virstoragefile.c (STORAGE_MAX_HEAD): ...old name.

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.
