- In between ntfs_prepare/commit_write, need exclusion between
simultaneous file extensions. This is given to us by holding i_sem
on the inode. The only places in the kernel when a file is resized
- are prepare/commit write and truncate for both of which i_sem is
- held. Just have to be careful in readpage/writepage and all other
- helpers not running under i_sem that we play nice...
- Also need to be careful with initialized_size extention in
- ntfs_prepare_write. Basically, just be _very_ careful in this code...
- UPDATE: The only things that need to be checked are read/writepage
- which do not hold i_sem. Note writepage cannot change i_size but it
- needs to cope with a concurrent i_size change, just like readpage.
- Also both need to cope with concurrent changes to the other sizes,
- i.e. initialized/allocated/compressed size, as well.

leave the volume dirty on umount if the final iput(vol->mft_ino)
causes a write of any mirrored mft records due to the mft mirror
