can you reproduce the dcache problem with this patch applied?

ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.2/2.2.20aa1/00_inode-boot-dynamic-3

The grow of the dcache in 2.2 is bound to the grow of the icache which
is not dynamic in 2.2. (modulo hardlinks but I don't think the guy was
using hardlinks)
