  fs/ntfs3: check for shutdown in fsync (2025-11-19 09:21:36 +0100)

----------------------------------------------------------------
Changes for 6.19-rc1

Added:
    support timestamps prior to epoch;
    do not overwrite uptodate pages;
    disable readahead for compressed files;
    setting of dummy blocksize to read boot_block when mounting;
    the run_lock initialization when loading $Extend;
    initialization of allocated memory before use;
    support for the NTFS3_IOC_SHUTDOWN ioctl;
    check for minimum alignment when performing direct I/O reads;
    check for shutdown in fsync.

Fixed:
    mount failure for sparse runs in run_unpack();
    use-after-free of sbi->options in cmp_fnames;
    KMSAN uninit bug after failed mi_read in mi_format_new;
    uninit error after buffer allocation by __getname();
    KMSAN uninit-value in ni_create_attr_list;
    double free of sbi->options->nls and ownership of fc->fs_private;
    incorrect vcn adjustments in attr_collapse_range();
    mode update when ACL can be reduced to mode;
    memory leaks in add sub record.

Changed:
    refactor code, updated terminology, spelling;
    do not kmap pages in (de)compression code;
    after ntfs_look_free_mft(), code that fails must put mi;
    default mount options for "acl" and "prealloc".

Replaced:
    use unsafe_memcpy() to avoid memcpy size warning;
    ntfs_bio_pages with page cache for compressed files.
