[PATCH] fs/btrfs: handle data extents, which crosss stripe boundaries, correctly

[Andreas Schwab]

The length returned by btrfs_map_block is clearly bogus:

read_extent_data: cur=615817216, orig_len=16384, cur_len=16384
read_extent_data: btrfs_map_block: cur_len=479944704; ret=0
read_extent_data: ret=0
read_extent_data: cur=615833600, orig_len=4096, cur_len=4096
read_extent_data: btrfs_map_block: cur_len=479928320; ret=0
