[-mm,0/2] nilfs2: eliminate the call to inode_attach_wb()

Message

Hi Andrew, please queue this series for the next cycle.

This series eliminates the inode_attach_wb() call from nilfs2, which
was introduced as a workaround for a kernel bug but is suspected of
layer violation (in fact, it is undesirable since it exposes a reference
to the backing device).

Removal of the inode_attach_wb() call is done by simply using
mark_buffer_dirty() on the backing device's buffers.  To use it safely,
this series will prepare it in patch 1/2, and perform the replacement
itself in patch 2/2.

Thanks,
Ryusuke Konishi

    checksums
  nilfs2: do not call inode_attach_wb() directly
