    Description

      Writes are accounted for, but not reads. The supplied patch fixes this.

      It seems that the accounting it normally done in the kernels page writeback and readahead
      functionality. Therefore as Lustre implements its own readahead, it must also maintain its own
      accounting on reads (but not writes).

          [Confluence: Engineering] Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA

            This conflict with RHEL5 is probably gone, should the patch be refreshed?
