      gfs2: Trim the ordered write list in gfs2_ordered_write() · 1f23bc78
      Abhi Das 提交于
      We iterate through the entire ordered writes list in
      gfs2_ordered_write() to write out inodes. It's a good
      place to try and shrink the list by throwing out inodes
      that don't have any pages.

      GFS2: Reduce code redundancy writing log headers · 588bff95
      Bob Peterson 提交于
      Before this patch, there was a lot of code redundancy between functions
      log_write_header (which uses bio) and clean_journal (which uses
      buffer_head). This patch reduces the redundancy to simplify the code
      and make log header writing more consistent. We want more consistency
      and reduced redundancy because we plan to add a bunch of new fields
      to improve performance (by eliminating the local statfs and quota files)
      improve metadata integrity (by adding new crcs and such) and for better
      debugging (by adding new fields to track when and where metadata was
      pushed through the journals.) We don't want to duplicate setting these
      new fields, nor allow for human error in the process.
      
      This reduction in code redundancy is accomplished by introducing a new
      helper function, gfs2_write_log_header which uses bio rather than bh.
      That simplifies recovery function clean_journal() to use the new helper
      function and iomap rather than redundancy and block_map (and eventually
      we can maybe remove block_map). It also reduces our dependency on
      buffer_heads.
