I think this patch is good, but just one concern from my. I just found This patch
might reduce test coverage of some filesystems. For example on nfs, the generic/116
test passed on nfsv4.2[1], but _notrun with this patch[2].
But that might be a problem of _get_file_block_size(), I don't learn about
nfs or other network-fs much, not sure how to get its "file alloc unit"
properly:)
Thanks,
Zorro
