      JFS: ext2 inode attributes for jfs · fa3241d2
      Herbert Poetzl authored
      ext2 inode attributes with relevance for jfs:
      
      'a' 	EXT2_APPEND_FL       -> append only
      'i' 	EXT2_IMMUTABLE_FL    -> immutable file
      's' 	EXT2_SECRM_FL	     -> zero file
      'u' 	EXT2_UNRM_FL	     -> allow for unrm
      'A' 	EXT2_NOATIME_FL      -> no access time
      'D' 	EXT2_DIRSYNC_FL      -> dirsync
      'S' 	EXT2_SYNC_FL	     -> sync
      
      overview of jfs flags (partially for OS/2)

      the implementation is straight forward, except
      for the fact that the attributes have to be mapped
      to match with the ext2 ones to avoid a separate
      tool for manipulating them (this could be avoided
      when using a separate flag field in the on-disk
      representation, but the overhead is minimal)
      
      a special jfs_ioctl is added to allow for the new
      JFS_IOC_GETFLAGS and JFS_IOC_SETFLAGS calls.
      
      a helper function jfs_set_inode_flags() to transfer
      the flags from the on-disk version to the inode
      
      minor changes to allow flag inheritance on inode
      creation, as well as a cleanup of the on-disk
      flags (including the new ones)
      
      beforementioned helper to map between ext2 and jfs
      versions of the new flags ...
      
      the JFS_SECRM_FL and JFS_UNRM_FL are not done yet
      and I'm not 100% sure they are worth the effort,
      the rest seems to work out of the box ...

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
