Perhaps this is related (from 2.4.10-acX thread later on l-k):

Read the ll_rw_blk diff. Basically it tries to avoid too many locked buffers clogging up memory and killing the box. I'm not totally sure its the right approach. --------
Were there recent changes in ll_rw_blk which are being addressed by "Elevator flow control"? As suggested earlier in this thread, the cause might be a few layers up, and this seemed relevant.
Can anyone confirm or shed any additional light on this?
