Hi Bruce,
I'm updating my fault injection patches to work with your recent stateid changes, and I had a question about something I'm seeing on the server. When I reboot the server it will enter a grace period and reply to any OPEN requests from the client with NFSERR_GRACE. I used Wireshark to see that NFSERR_GRACE is returned 12 times before the open succeeds, so 13 OPEN requests total. When I send the command to forget all open owners I find that 13 open owners have been forgotten, but I only expecting to find 1. Is this what you would expect the server to do?
I've pasted the code I use to count and delete open owners below. The variable "num" has the value 0, so all open owners should be deleted.
- Bryan
static int nfsd_forget_n_openowners(u64 num)
{
int i, count = 0;
struct nfs4_stateowner *sop, *next;
for (i = 0; i < OPEN_OWNER_HASH_SIZE; i++) {
list_for_each_entry_safe(sop, next, &open_ownerstr_hashtbl[i], so_strhash) {
release_openowner(openowner(sop));
if (++count == num)
return count;
}
}
return count;
}
void nfsd_forget_openowners(u64 num)
{
int count;
nfs4_lock_state();
count = nfsd_forget_n_openowners(num);
nfs4_unlock_state();
printk(KERN_INFO "%s %s Forgot %d open owners", __FILE__, __func__, count);
}
