[RFC] xfs: drop experimental warning for fsdax

Commit Message

Since reflink&fsdax can work together now, the last obstacle has been
resolved.  It's time to remove restrictions and drop this warning.

I haven't looked at reflink+DAX for some time, and I haven't tested
it for even longer. So I'm currently running a v6.0-rc6 kernel with
"-o dax=always" fstests run with reflink enabled and it's not
looking very promising.

All of the fsx tests are failing with data corruption, several
reflink/clone tests are failing with -EINVAL (e.g. g/16[45]) and
*lots* of tests are leaving stack traces from WARN() conditions in
DAx operations such as dax_insert_entry(), dax_disassociate_entry(),
dax_writeback_mapping_range(), iomap_iter() (called from
dax_dedupe_file_range_compare()), and so on.

At thsi point - the tests are still running - I'd guess that there's
going to be at least 50 test failures by the time it completes -
in comparison using "-o dax=never" results in just a single test
failure and a lot more tests actually being run.

Given that a non-reflink DAX filesystem doesn't seem to have all
these problems, it's pointing to the dax+reflink interactions still
containing various bugs. Unless I'm doing something obviously wrong
that causes all these problems, I really don't think this code is
production ready.

We really need reflink enabled DAX filesystems to pass fstests
cleanly before we can remove the experimental tag, so if you've got
any ideas what is causing the stack traces and data corruptions
below, I'm all ears...

-Dave.

The end results with dax+reflink were:

Ok, so I did a new no-reflink run as a baseline, because it is a
while since I've tested DAX at all:

Yeah, there's still lots of warnings from dax_insert_entry() and

So it looks to me like DAX is well and truly broken in 6.0-rc6. And,
yes, I'm running the fixes in mm-hotifxes-stable branch that allow
xfs/550 to pass.

Who is actually testing this DAX code, and what are they actually
testing on? These are not random failures - I haven't run DAX
testing since ~5.18, and none of these failures were present on the
same DAX test VM running the same configuration back then....

Thanks for testing.  I just ran the xfstests and got these failures too. 
  The failure at dax_insert_entry() appeared during my development but 
was fixed before I sent the patchset.  Now I am looking for what's wrong 
with it.

BTW, which groups did you test?  I usually test quick,clone group.

These are auto group runs, as I normally do for testing patches.

I have tested these two mode for many times:

xfs_dax mode did failed so many cases.  (If you tested with this "drop" 
patch, some warning around "dax_dedupe_file_range_compare()" won't occur 
any more.)  I think warning around "dax_disassociate_entry()" is a 
problem with concurrency.  Still looking into it.

But xfs_dax_noreflink didn't have so many failure, just 3 in my 
environment: Failures: generic/471 generic/519 xfs/148.  I am thinking 
that did you forget to reformat the TEST_DEV to be non-reflink before 
run the test?  If so it will make sense.

So, yeah, reflink was turned off on both test and scratch devices,
and dax=always on both the test and scratch devices was used to
ensure that DAX was always in use.

Yup, that's the same as what I'm seeing.

Could you send me your kernel config (or other configs needed for the 
test)?  I still cannot reproduce this warning when reflink is off, even 
without this drop patch.  Maybe something different in config file?


PS: I specifically tried the two cases Darrick mentioned (on v6.0-rc6):

I'm not sure what exactly is going weird here -- I tried it on my dev
machine just now and it passed, but the similarly configured testcloud
failed it last night.

FSTYP         -- xfs (debug)
PLATFORM      -- Linux/x86_64 ca-nfsdev6-mtr03 6.0.0-rc7-xfsx #rc7 SMP
PREEMPT_DYNAMIC Wed Sep 28 15:35:58 PDT 2022
MKFS_OPTIONS  -- -f -m reflink=0, -d daxinherit=1, /dev/pmem1
MOUNT_OPTIONS -- -o usrquota,grpquota,prjquota, /dev/pmem1 /opt

Note that I use libvirt to configure pmem in the VMs.  This is an

Ping?

This time around I replaced the WARN_ON with this:

	if (page->mapping)
		printk(KERN_ERR "%s:%d ino 0x%lx index 0x%lx page 0x%llx mapping 0x%llx <- 0x%llx\n", __func__, __LINE__, mapping->host->i_ino, index + i, (unsigned long long)page, (unsigned long long)page->mapping, (unsigned long long)mapping);

and promptly started seeing scary things like this:

I'm not sure what's going on here, but we're clearly turning COW daxpages
back into single-mapping daxpages.  I'm not sure what's going on for the
cases where we're replacing one mapping with another.  My dimwitted
guess is that dax_fault_is_cow() is incorrectly returning false in some
cases.

Replacing the contents of that function with:

	if (iter->srcmap.type != IOMAP_HOLE)
		return true;
	if (iter->iomap.flags & IOMAP_F_SHARED)
		return true;
	return false;

Doesn't make the errors go away.  Curiously, replacing the entire
function body with "return true;" fixes /that/ problem though...

...but generic/649 still fails with things like:

[  571.224285] run fstests generic/649 at 2022-10-13 11:26:59

[  572.379598] WARNING: CPU: 1 PID: 48538 at fs/dax.c:930 dax_writeback_mapping_range+0x2f1/0x600

Which comes from this warning in dax_writeback_one:

	/*
	 * A page got tagged dirty in DAX mapping? Something is seriously
	 * wrong.
	 */
	if (WARN_ON(!xa_is_value(entry)))
		return -EIO;

Help?

I am looking into this error by adding debug message too.  I found that 
testcases which execute fsstress will randomly occur this error.  I'm 
guessing some concurrent operations caused the cow flag (returned by 
dax_fault_is_cow()) to be incorrectly judged.  But still haven't catch 
the exactly operation yet.

Sorry, no time for this yet...

BTW, are these errors still occur when reflink is turned off? (dax on, 
reflink off)

I have an offhand guess that the following sequence might reproduce it:

<write data to a fsdax file1>

<process 1 maps file1, which sets up the pagecache mapping to pmem, and
goes to sleep>

cp --reflink=always file1 file2

<process 2 maps file2, which tries to map the same pmem "page" into
file2's pagecache and trips over page->mapping already being set to
file1's pagecache>

But I dunno, I haven't had much time for digging into this one.

I tried it on 6.1-rc1 and ... it seems to have gone away.

I add this in my local.config:
