      nilfs2: get rid of nilfs_sb_info structure · e3154e97
      Ryusuke Konishi 提交于
      This directly uses sb->s_fs_info to keep a nilfs filesystem object and
      fully removes the intermediate nilfs_sb_info structure.  With this
      change, the hierarchy of on-memory structures of nilfs will be
      simplified as follows:
      
      Before:
        super_block
             -> nilfs_sb_info
                   -> the_nilfs
                         -> cptree --+-> nilfs_root (current file system)
                                     +-> nilfs_root (snapshot A)
                                     +-> nilfs_root (snapshot B)
                                     :
                   -> nilfs_sc_info (log writer structure)
      After:
        super_block
             -> the_nilfs
                   -> cptree --+-> nilfs_root (current file system)
                               +-> nilfs_root (snapshot A)
                               +-> nilfs_root (snapshot B)
                               :
                   -> nilfs_sc_info (log writer structure)
      
      The reason why we didn't design so from the beginning is because the
      initial shape also differed from the above.  The early hierachy was
      composed of "per-mount-point" super_block -> nilfs_sb_info pairs and a
      shared nilfs object.  On the kernel 2.6.37, it was changed to the
      current shape in order to unify super block instances into one per
      device, and this cleanup became applicable as the result.

      nilfs2: fiemap support · 622daaff
      Ryusuke Konishi 提交于
      This adds fiemap to nilfs.  Two new functions, nilfs_fiemap and
      nilfs_find_uncommitted_extent are added.
      
      nilfs_fiemap() implements the fiemap inode operation, and
      nilfs_find_uncommitted_extent() helps to get a range of data blocks
      whose physical location has not been determined.
      
      nilfs_fiemap() collects extent information by looping through
      nilfs_bmap_lookup_contig and nilfs_find_uncommitted_extent routines.
