[RFC] A new dm-loop implementation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



And an alternative to losetup some of you might like to experiment with:

  http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/
    dm-extract-device-limit-setting.patch
    dm-table-add-target-flush.patch  
      (requires dm-table-add-target-preresume.patch first to apply cleanly)
    dm-add-loop.patch
    dm-loop.patch

losetup /dev/loop0 /tmp/file
  becomes roughly
dmsetup create loop0 --table "0 N loop /tmp/file 0"
  --table option is now in cvs; else use stdin
  N is the <filesize_in_bytes>/512
  make file a multiple of your page size & fs block size
We're working towards a drop-in replacement for 'losetup'.
