Btrfs: btrfs_mark_extent_written uses the wrong slot
My test do: fallocate a big file and do write. The file is 512M, but after file write is done btrfs-debug-tree shows: item 6 key (257 EXTENT_DATA 0) itemoff 3516 itemsize 53 extent data disk byte 1103101952 nr 536870912 extent data offset 0 nr 399634432 ram 536870912 extent compression 0 Looks like a regression introducted by 6c7d54ac87f338c479d9729e8392eca3f76e11e1, where we set wrong slot.
