I am obsering a steadily increasing buffer_head value in slabinfo under
2.6.17.4. I searched the net / archives and didn't find anything
directly relevant. Does anyone have an idea or how shall we debug it?

The problem is still there under 2.6.18-rc2. I narrowed it down to ext3journal. To reproduce one just has to mount an ext3 partition and perform(write) accesses to it. A loop { touch /mnt/foo; sleep 1; } suffices -just let it run for a couple of minutes and monitor buffer_head in/proc/slabinfo. If you mount it as ext2 the problem is gone.


Thanks
