backing_dev: remove current->backing_dev_info
Patch series "cleanup the filemap / direct I/O interaction", v4.
This series cleans up some of the generic write helper calling conventions
and the page cache writeback / invalidation for direct I/O. This is a
spinoff from the no-bufferhead kernel project, for which we'll want to an
use iomap based buffered write path in the block layer.
This patch (of 12):
The last user of current->backing_dev_info disappeared in commit
b9b1335e6403 ("remove bdi_congested() and wb_congested() and related
functions"). Remove the field and all assignments to it.
