btrfs-progs: convert: Fix a bug which fails to insert hole file extent
When copying inode, if there is a file referring part of a hole range, convert will fail. The problem is, when calculating real extent bytenr, it doesn't check if the original extent is a hole. In case the orinal extent is a hole, we still calculate bytenr using file_pos - found_extent_file_pos, causing non-zero value, and later btrfs_record_file_extent() detects that we are pointing to non-exist extent and aborts convert. Fix it by checking the disk_bytenr before calculating real disk bytenr. Signed-off-by: Qu Wenruo <> Signed-off-by: David Sterba <>
