Description of problem: The dht rename codepath has a severe leak if it needs to create a linkto file. Version-Release number of selected component (if applicable): How reproducible: Consistently Steps to Reproduce: 1. Create a 2x3 distribute replicate volume and fuse mount it. 2. Create 2 directories, dir1 and dir1-new in the root of the volume 3. Find 2 filenames which will hash to different subvols when created in these directories. For example, in my setup dir1/file-1 and dir1-new/newfile-1 hash to different subvols. This is necessary as the leak is in the path which creates a linkto file. 4. Run the following script and watch the memory usage for the mount process using top. Actual results: Memory rises steadily. Statedumps show that the number of active inodes keeps increasing. Expected results: Memory should not increase as there is a single file on the volume. Additional info: This is a regression introduced by https://code.engineering.redhat.com/gerrit/#/c/154933/ in RHGS 3.4.2
