This patch removes the call to vol update after the volume build completes.
The update call is currently meaningless anyway because the vol build is passed
a copy of the definition, so the update result is thrown away. More
importantly, if the user specified a selinux label for the volume, the update
call results in a double free of the label
* src/storage/storage_backend_fs.c: remove the update call
* src/storage/storage_backend_fs.c: virStorageBackendFileSystemDelete
was incorrectly calling unlink() in an attempt to remove a directory.
It should be calling rmdir() instead.
Finally, we get to the point of all this.
Move virStorageGetMetadataFromFD() to virStorageFileGetMetadataFromFD()
and move to src/util/storage_file.[ch]
There's no functional changes in this patch, just code movement
* src/storage/storage_backend_fs.c: move code from here ...
* src/util/storage_file.[ch]: ... to here
* src/libvirt_private.syms: export virStorageFileGetMetadataFromFD()
Introduce a metadata structure and make virStorageGetMetadataFromFD()
fill it in.
* src/util/storage_file.h: add virStorageFileMetadata
* src/backend/storage_backend_fs.c: virStorageGetMetadataFromFD() now
fills in the virStorageFileMetadata structure
Prepare the code probing a file's format and associated metadata for
moving into libvirt_util.
* src/storage/storage_backend_fs.c: re-factor the format and metadata
probing code in preparation for moving it
Rename virStorageVolFormatFileSystem to virStorageFileFormat and
move to src/util/storage_file.[ch]
* src/Makefile.am: add src/util/storage_file.[ch]
* src/conf/storage_conf.[ch]: move enum from here ...
* src/util/storage_file.[ch]: .. to here
* src/libvirt_private.syms: update To/FromString exports
* src/storage/storage_backend.c, src/storage/storage_backend_fs.c,
src/vbox/vbox_tmpl.c: update for above changes
