I have noticed a regression in lts test case with nfsv4 and this was 
overlooked in the previous cycle(5.15.154). So the regression is from 
153-->154 update. And I think that is due to nfs backports we had in 
5.15.154.

This does not happen in 5.15.153 tag.

The reproducer uses NFSv3, but the bug report says NFSv4
at the top.

I was able to reproduce this on my nfsd-5.15.y branch
with NFSv3.

A bisect would be most helpful.

I was able to bisect: here are the results:



2267b2e84593bd3d61a1188e68fba06307fa9dab is the first bad commit
commit 2267b2e84593bd3d61a1188e68fba06307fa9dab
Author: Alexander Aring <aahringo@redhat.com>
Date:   Tue Sep 12 17:53:18 2023 -0400

     lockd: introduce safe async lock op

     [ Upstream commit 2dd10de8e6bcbacf85ad758b904543c294820c63 ]

     This patch reverts mostly commit 40595cdc93ed ("nfs: block notification
     on fs with its own ->lock") and introduces an EXPORT_OP_ASYNC_LOCK
     export flag to signal that the "own ->lock" implementation supports
     async lock requests. The only main user is DLM that is used by GFS2 and
     OCFS2 filesystem. Those implement their own lock() implementation and
     return FILE_LOCK_DEFERRED as return value. Since commit 40595cdc93ed
     ("nfs: block notification on fs with its own ->lock") the DLM
     implementation were never updated. This patch should prepare for DLM
     to set the EXPORT_OP_ASYNC_LOCK export flag and update the DLM
     plock implementation regarding to it.

I didnot test the revert of culprit commit on top of 5.15.154 yet.

Nice work. Thanks!

Please try reverting that one -- it's very close to the top so one
or two others might need to be pulled off as well.

I expect this is due to a missing pre-requisite commit.

I have reverted the bad commit: 2267b2e84593 ("lockd: introduce safe 
async lock op") and the test passes.

Note: Its reverts cleanly on 5.15.154

Harshit also informs me that "lockd: introduce safe async lock op"
is not applied to v6.1, so it's not likely necessary to include here
and can be safely reverted from v5.15.y.

Chuck, can you send a series of reverts for what needs to be done here
as these were your original backports?

Interestingly, this same LTP fcntl17 test failure was reported to me 
internally some time back, in late 2022; at the time it was bisected to:

6930bcbfb6ce lockd: detect and reject lock arguments that overflow
	mainline v6.0-rc1
	stable v5.15.61

However, the failure was intermittent, and seemed very dependent on test 
system configuration; eventually it disappeared, so I put it down to 
test issues.


Harshit will continue to bisect this new case.

Any way you can run 'git bisect' to find the offending change?  There's
a lot to dig through :(

I wanted to repeat my request from another thread[1] here, that we revert commit 4949affd5288 
("ACPI: CPPC: Use access_width over bit_width for system memory accesses") in 5.15.155 due to
known problems with the patch, so it's not lost in the mail storm.

Thanks,
Easwar
