[PATCH v2 0/4] btrfs-progs: add support ext4 unwritten file extent

[Anand Jain <anand.jain@oracle.com>]

v2:
 Fix per review comments.
 Identify and fail safe prealloc merged with regular blocks.

These patches add support for the ext4 file data unwritten/preallocated
extents. Patches 1-3 are preparatory patches, and patch 4 adds the
missing feature.

Patch 4 is marked as RFC because this patch is tested with limited
variants of the file extents with unwritten flag.


Anand Jain (4):
  btrfs-progs: convert: refactor ext2_create_file_extents add argument
    ext2_inode
  btrfs-progs: convert: struct blk_iterate_data, add ext2-specific file
    inode pointers
  btrfs-progs: convert: refactor __btrfs_record_file_extent to add a
    prealloc flag
  btrfs-progs: convert: support ext2 unwritten file data extents
