Hi all, This is a series to update the "create file and preallocate blocks" code in xfs_restore. The first patch refactors the existing copy-pasta into a single helper function to create and preallocate space in files, as well as removing the totally broken ALLOCSP code. The next two patches fix unchecked return values and insufficient unsupported-ioctl code. The final patch upgrades xfs_restore to try fallocate before RESVSP simply because it is the newer API. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D
