    Description

      We have an optimization that replaces bmap calls with fiemap calls through the brw path.

      A patch will be uploaded shortly.

      The patch also includes a fix for a fiemap deadlock in pre 3.8 kernels. This deadlock can happen without this fiemap optimization as well - through FIEMAP get_info RPC.
