    Subject[PATCH 5.18 021/879] fs/ntfs3: provide block_invalidate_folio to fix memory leak
    Date
    From: Mikulas Patocka <mpatocka@redhat.com>

    commit 724bbe49c5e427cb077357d72d240a649f2e4054 upstream.

    The ntfs3 filesystem lacks the 'invalidate_folio' method and it causes
    memory leak. If you write to the filesystem and then unmount it, the
    cached written data are not freed and they are permanently leaked.
    Fixes: 7ba13abbd31e ("fs: Turn block_invalidatepage into block_invalidate_folio")
