Linus,
You forgot about wakeup_bdflush(1) stuff.
Here is the patch again (against test10).
===
There are several places where schedule() is called after wakeup_bdflush(1)
is called. This is completely unnecessary, since wakeup_bdflush(
Neil,
Here is a set of fixes and answers to you questions/points. The new patch
was tested in my own environment again and worked fine.
1/ Why did you change nfsd_busy into an atomic_t? It is only ever
used or updated inside the Big-Kernel-Lock, so it doesn't need
to be atomic.
I think
Hi,
This is the recoded racache that uses list_head for several lists, e.g.,
lru and free lists. I have tested it under SPEC SFS runs, and several other
NFS loads myself.
Here is the whole patch against test10.
=
diff -ruN nfsd.orig/nfsd.h nfs
1/ Do you have any stats showing what sort of speedup this gives -
I'm curious.
I don't have the exact timing stats to show the improvements, but I do have
some stats that I gathered when running SPEC SFS.
Basically with the default racache scheme which only keeps 80 entries in
the table
Hi,
I'm wondering if someone can tell me why sync_all_inodes() is called in
prune_icache().
sync_all_inodes() can cause problems in some situations when memory is
short and shrink_icache_memory() is called.
For instance, when the system is really short of memory,
do_try_to_free_pages() is invoked
scanning the table (even
though the table is small), the hash table-based is much more effective
and fast. I have generated the patch for test10 and tested it.

Hi,
I made some optimizations on racache in nfsd in test10. The idea is to
replace with existing fixed length table for readahead cache in NFSD with a
hash table.
The old racache is essentially ineffective in dealing with large # of
files, and yet eats CPU cycles in scanning the table (even thoug
nsigned long address,
pte_t *page_table, pte_t entry)
{
-flush_tlb_page(vma, address);
set_pte(page_table, entry);
+flush_tlb_page(vma, address);
update_mmu_cache(vma, address, entry);
}

I'd second that this is most likely a VM related problem. Last few days I
sent you an example that I would make system hang simply by
doing a mkfs on 90 GB file system. This happens when low 1GB memory is used
up (but I still have high 1GB available). I think
David probably ran into the same prob
