The\nreport below is triggered by a simple program 'tmpfile' just opening a\ntmpfile:\n\n unreferenced object 0xffff88810178f380 (size 32):\n comm \"tmpfile\", pid 509, jiffies 4294934744 (age 1524.742s)\n backtrace:\n __kmem_cache_alloc_node\n __kmalloc\n fscrypt_setup_filename\n ubifs_tmpfile\n vfs_tmpfile\n path_openat\n\nFree this memory after it has been copied to the inode."
