- - Modify fs/ntfs/malloc.h::ntfs_malloc_nofs() to do the kmalloc() based
- allocations with __GFP_HIGHMEM, analogous to how the vmalloc() based
- allocations are done.
- Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to
ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and
hence cannot fail.
