[Lustre-discuss] Lustre 1.8 patched kernel for RHEL5 clients?

[Alex Lyashkov]

Hello,

for clients, main difference is two patches -
first is adjust stack size to 8k, this need for run nfs and lustre
clients at same node, otherwise can be stack overflow.
second patch is light changes in dcache - which allow less tricky work
with dcache.

any big performance changes should be don't exist.
