That's one of the basic differences between the 2.2.x and 2.4.x
page cache design. We don't reclaim the buffers at I/O completion
time anymore in 2.4.x but we reclaim them only later when we run
low on memory.

Forbidding the bh to be reclaimed when we run low on memory is a bug
and I don't think Linus ever suggested that.
