    nilfs2: keep zero value in i_cno except for gc-inodes · 6c43f410
    Ryusuke Konishi authored
    On-memory inode structures of nilfs have a member "i_cno" which stores
    a checkpoint number related to the inode.  For gc-inodes, this field
    indicates version of data each gc-inode caches for GC.  Log writer
    temporarily uses "i_cno" to transfer the latest checkpoint number.
    
    This stops the latter use and lets only gc-inodes use it.
    
    The purpose of this patch is to allow the successive change use
    "i_cno" for inode lookup.
