Fwd: xfstest results

[Steve French <smfrench@gmail.com>]

With the first four netfs patches + 6.14-rc7 running our standard
regression tests to Azure with multichannel, I saw a couple of
unexpected failures.

23dbb8c5ffaf netfs: Fix netfs_unbuffered_read() to return ssize_t
rather than int
78067c2bd7f9 netfs: Fix rolling_buffer_load_from_ra() to not clear mark bits
6be938f6c265 netfs: Call `invalidate_cache` only if implemented
5fb49e95f2c2 netfs: Fix collection of results during pause when
collection offloaded

and also test generic/738

But with all six current netfs patches (including the two additional below):
68109110fec1 netfs: Fix wait/wake to be consistent about the waitqueue used
4f8443992c8c netfs: Fix the request's work item to not require a ref

I see a hang early on e.g. in cifs/100 then in cifs/103 (and all
following cifs/105 generic/001 etc).  I don't see anything useful in
/var/log/messages

I don't see anything suspicious in /proc/fs/cifs/DebugData but in
/proc/fs/cifs/Stats I do see it shows a session reconnect, and I do
see a suspicious number of open files (which oddly enough is created
by an earlier test, before the hang cifs/100)

          Open files: 1 total (local), -2 open on server

root@fedora29:~# cat /proc/fs/cifs/open_files
# Version:1
# Format:
# <tree id> <ses id> <persistent fid> <flags> <count> <pid> <uid>
<filename> <mid>
0x5 0x792a00b20000a11 0x56ce090b 0x8001 2 5497 0 big-file 23

I will also try a more general test run to see if I can reproduce
anything useful with those
