[GIT PULL] fs meta data unmap

[GIT PULL] fs meta data unmap

[Jens Axboe]

Hi Linus,

A series from Jan Kara, providing a more efficient way for unmapping
meta data from in the buffer cache than doing it block-by-block. Provide
a general helper that existing callers can use.

Please pull!

Jan Kara (6):
      fs: Provide function to unmap metadata for a range of blocks
      direct-io: Use clean_bdev_aliases() instead of handmade iteration
      ext4: Use clean_bdev_aliases() instead of iteration
      ext2: Use clean_bdev_aliases() instead of iteration
      fs: Add helper to clean bdev aliases under a bh and use it
      fs: Remove unmap_underlying_metadata
