This was an omission from commit 26c3679101dbccc054dcf370143941844ba70531 "fuse: destroy bdi on umount", which moved the bdi_destroy() call from fuse_conn_put() to fuse_put_super().

mm: page_mkwrite change prototype to match fault 2009-04-01T15:59:14+00:00 Nick Piggin npiggin@suse.de 2009-03-31T22:23:21+00:00 c2ec175c39f62949438354f603f4aa170846aabb Change the page_mkwrite prototype to take a struct vm_fault, and return VM_FAULT_xxx flags. There should be no functional change. This makes it possible to return much more detailed error information to the VM (and also can provide more information eg. virtual_address to the driver, which might be important in some special cases). This is required for a subsequent fix. And will also make it easier to merge page_mkwrite() with fault() in future.
