Any later failure inside load_system_files() leaks it.\n\n  - vol->lcn_empty_bits_per_page was kvfree()'d in\n    unl_upcase_iput_tmp_ino_err_out_now without clearing the pointer,\n    so it could not be folded into a single common cleanup.\n\nBecause the failure paths never call ntfs_volume_free() and never reach\nthe d_make_root() inline cleanup block (it sits above the label and is\njumped over by the load_system_files() / kvmalloc failure gotos), these\nresources accumulate per failed mount attempt with no chance of\nrecovery short of unloading the module.  This is a silent leak: the\ninodes loaded prior to failure remain hashed but generic_shutdown_super()\nskips evict_inodes() when sb->s_root is unset, so no CHECK_DATA_CORRUPTION\nwarning is emitted either.\n\nMove the per-volume frees down to err_out_now and drop the\nlcn_empty_bits_per_page kvfree() from the upper label so the cleanup is\nperformed exactly once on every failure path.  Using unconditional\nkvfree() / kfree() / unload_nls() is safe because they all accept NULL\nand the upper labels that previously freed nls_map (the d_make_root()\ninline cleanup) already clear the pointer."
