This issue is actually deeper and not specific to gso.
With corking it is trivial to turn off sg in between calls.
I'll need to send a separate fix for that.

Well, I wrote it, so it's in my repo now ;-). I just sent it to the
list because that's what you do when you are writing fixup patches even
if you've already committed them.

I just sent an incremental fix to the list under separate cover. You
can squash that fix into Steve's patch and it should resolve the issue.
Or Steve can respin the set. Either way.

From: MRS NUBIA MUHAMMAD @ 2018-05-15 19:57 UTC (permalink / raw)
Dearest,
Greetings in the name of Allah,please let this not sound strange to
you for my only surviving lawyer who would have done this died early
this year.I prayed and got your email id from your country guestbook.I
am Mrs Nubia Muhammad from Egypt,I am 72 year old,i am suffering from
a long time cancer of the lungs,from all indication my conditions is
really deteriorating and it is quite obvious that,according to my
doctors they have advised me that i may not live for more than two
months,this is because the cancer stage has gotten to a very bad
stage.I am married to Late (Muhammad Essem Shafik) who was former
Embassy of the Arab Republic of Egypt in South Africa for nine
years,Before he died in 2005.
I married to my late husband for Thirty years without a child,my
husband died in a fatal motor accident Before his death we were truely
Islamic believers.Since his death I decided not to re-marry,I sold all
my inherited belongings and deposited all the sum of £5.2 Millions GBP
Pounds with Bank in South Africa.Though what disturbs me mostly is the
cancer.Having known my condition I decided to donate this fund to
you,i want you as ALLAH fearing person,to also use this money to
Help,orphanages and widows,I took this decision,before i rest in peace
because my time will so on be up.
I took this decision because I don`t have any child that will inherit
this money and my husband's relatives are not around and I don`t want
my husband hard earned money to go invain. I don`t want a situation
where these money will be misused,hence the reason for taking this
bold decision.I am not afraid of death hence i know where am going to
ALLAH.Presently,I'm with my laptop in a hospital here in London where
I have been undergoing treatment for cancer of the lungs.
As soon as I receive your reply I shall give you the contact of the
Bank.I will also issue you a letter of authority that will prove you
as the new beneficiary of my fund.Please assure me that you will act
accordingly as I stated.Hoping to hear from you soon.
May Allah bless you.
Mrs Nubia Muhammad

sure for the above, but not the ones below.
Before this patch, this program:
$ cat a.c
#include <uapi/rdma/rdma_netlink.h>
#include <stdio.h>
int main(void)
{
printf("RDMA_NLDEV_ATTR_NDEV_INDEX = %d\n", RDMA_NLDEV_ATTR_NDEV_INDEX);
return 0;
}
prints this:
$ ./a.out
RDMA_NLDEV_ATTR_NDEV_INDEX = 50
After this patch,
$ ./a.out
RDMA_NLDEV_ATTR_NDEV_INDEX = 58

This chunk, however, is a problem. We'll need to fix that in the kernel
and in this patch too.

In-Reply-To: <20180515194833.6906-1-hch@lst.de>
The big change is that random_read_wait and random_write_wait are merged
into a single waitqueue that uses keyed wakeups. Because wait_event_*
doesn't know about that this will lead to occassional spurious wakeups
in _random_read and add_hwgenerator_randomness, but wait_event_* is
designed to handle these and were are not in a a hot path there.
