Hi folks,

Just pulled the latest Linus kernel and running it through
check-parallel on a 1kB block size filesystem throws a lots of these
warnings:

I'm also seeing them from inodegc worker threads via:

  xfs_reflink_cancel_cow_range+0x79/0x200
  xfs_inactive+0x188/0x3b0
  xfs_inodegc_worker+0xaa/0x180
  process_scheduled_works+0x1d6/0x400

The warning is:

	WARN_ON(mp->m_super->s_writers.frozen == SB_FREEZE_COMPLETE);

Which indicates that we are doing inodegc on a frozen filesystem.
We should have called xfs_inodegc_stop() from xfs_fs_sync_fs() once
all data modification had been frozen and written back at
SB_FREEZE_PAGEFAULT level....

Ah, just got the same warning from xfs_quota_normap config, which is
running a 4kB block size filesystem. So it has nothing to do with
the filesystem block size. Looks like a freeze regression, then?

Hmmm - this warning is in code that was modified in this merge
window.  Specifically, commit 83a80e95e797 ("xfs: decouple
xfs_trans_alloc_empty from xfs_trans_alloc") that was merged in the
merge window changes how this specific warning is triggered...

Christoph, looks like this is one for you - these transactions
previously got caught in sb_start_intwrite() before the freeze state
warning check (i.e. modifications get blocked once freeze starts, so
never get to the warning whilst the fs is frozen). The new code
checks the freeze state and emits the warning before the transaction
can (correctly) account/block on freeze state via
sb_start_intwrite().

-Dave.

Yeah, the WARN_ON should move down.  I'll prepare a patch.

FWIW, I *just* hit the assertion below on generic/475 running with 1k
blocks:

My apologies for not having much more information, I didn't have time to debug
it yet. I'm posting it here for broader audience by now as I haven't seen this
before, I'll try to find some time to look more into it.
