Kevin Wolf 738301e117 file-posix: Support BDRV_REQ_NO_FALLBACK for zero writes ... We know that the kernel implements a slow fallback code path for BLKZEROOUT, so if BDRV_REQ_NO_FALLBACK is given, we shouldn't call it. The other operations we call in the context of .bdrv_co_pwrite_zeroes should usually be quick, so no modification should be needed for them. If we ever notice that there are additional problematic cases, we can still make these conditional as well.
