commit commit 02f312754c873efe076888a2fdca982e56617929 Author: YangWen Date: Wed Sep 10 23:17:08 2025 +0800 ntfs3: fix use-after-free of sbi->options in cmp_fnames The root cause is that sbi->options points directly to fc->fs_private. If fc->fs_private is freed while sbi still exists, sbi->options becomes a dangling pointer. This patch ensures that sbi->options is a separate copy of fc->fs_private and duplicates nls_name if present. On superblock release or error, sbi->options->nls_name and sbi->options are freed and sbi->options is set to NULL to avoid any dangling pointer.
