"metadata I/O error in ("\%s\") at daddr 0x%llx len %d error %d"
also:
"%s: daddr out of range: block 0x%llx, EOFS 0x%llx ", __func__, b_bn, eofs
"%s: no ops on buf for daddr 0x%llx/0x%x", __func__, b_bn, b_length
"Corruption Alert: Buffer at daddr 0x%llx had permanent write failures!"
So I guess it's also not consistent how we print buffer length either?
I'll work on something to clean all this up...
