Test that if we rename a file, without changing its parent directory, create a new file that has the old name of the file we renamed, doing an fsync against the file we renamed works correctly and after a power failure both files exists. This is motivated by an issue found in btrfs, introduced in the linux kernel 4.8-rc2, that caused lockdep to report a deadlock scenario. The btrfs issue is fixed by the patch titled: "Btrfs: fix lockdep warning on deadlock against an inode's log mutex" Tested against ext3/4, xfs, f2fs and reiserfs as well.
