fs: reiserfs: remove useless new_opts in reiserfs_remount
Since the commit c3d98ea08291 ("VFS: Don't use save/replace_mount_options if not using generic_show_options") eliminates replace_mount_options in reiserfs_remount, but does not handle the allocated new_opts, it will cause memory leak in the reiserfs_remount. Because new_opts is useless in reiserfs_mount, so we fix this bug by removing the useless new_opts in reiserfs_remount. Fixes: c3d98ea08291 ("VFS: Don't use save/replace_mount_options if not using generic_show_options") Link: https://lore.kernel.org/r/20211027143445.4156459-1-mudongliangabcd@gmail.com Signed-off-by: Dongliang Mu <mudongliangabcd@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>
