This tests that we can not clone an inline extent into a non-zero file offset. Inline extents at non-zero offsets is something btrfs is not prepared for and results in all sorts of corruption and crashes on future IO operations, such as the following BUG_ON() triggered by the last write operation done by this test: [152154.035903] ------------[ cut here ]------------ [152154.036424] kernel BUG at mm/page-writeback.c:2286!
