Benny Hi
I have a problem that the default wsize is very small 64K and
I get small IOs. I found that the governing member right now
is NFS_SERVER()->wsize
I did the below hack on My current code, but you took that away
from me.
diff --git a/fs/nfs/objlayout/objlayout.c b/fs/nfs/objlayout/objlayout.c
index ec40408..f7b09e1 100644
--- a/fs/nfs/objlayout/objlayout.c
+++ b/fs/nfs/objlayout/objlayout.c
+ server->wsize = ((PAGE_SIZE - sizeof(struct bio)) / sizeof(struct bio_vec))
+ * PAGE_SIZE * 2;
- dprintk("%s: Return data=%p\n", __func__, data);
+ dprintk("%s: Return data=%p wsize=0x%x\n", __func__, data, server->wsize);
return 0;
}
What do you want that we do to replace this. The default 64K is to small.
I don't mind that for pnfs it will be ~0 and the pg_test() will test
for maxc_size as well. But then we'll also need the current size or the
start_index
