Hi,

ocfs2 crashes most of the times when I try to create a lot of files on
the filesystem. The details are:

Arch: i686 (2 processors)
Kernel version: 2.6.35.3
Script to reproduce:
for i in `seq 1 1048576`; do echo $i > f.$i; done
Reproducible: most of the times
fs-features: indexed-dirs,local,noxattr

dmesg:

Hi Goldwyn,

I was able to reproduce the issue in my local box.

Thanks for reporting, we'll look into this!

  Doh, this is
J_ASSERT_JH(jh, jh->b_next_transaction == transaction);
  in your kernel, right? That would be really really strange. Tristan,
if you can reproduce, it would be interesting to find out where
"b_next_transaction" points to and where "transaction" points to. There is
now way how there could be two running transactions in JBD2 so one of the
pointers must be wrong...

So no matter what the transaction(which owns the buffer's metadata) is, 
committing or running.

The 'b_next_transaction' was always expected to point to the current 
running transaction, whereas
in this case, it showed address of affected pointers as follows when BUG 
occurs:

transcation = ffff880135d64bc0, jh->b_transaction = ffff880135d645c0, 
jh->b_next_transaction = (null),
journal->j_committing_transaction = ffff880135d645c0

Btw, I'm afraid to say it's a BUG which probably was introduced by 
'index-dirs'. NONE index-dirs fs never hit this before.

  Hmm, so it most probably looks as if we modify a buffer for which we
didn't call ocfs2_journal_access_?? From a quick look, suspicious places
are ocfs2_recalc_free_list, ocfs2_remove_block_from_free_list (but probably
not the cause of this particular oops), and ocfs2_dx_dir_transfer_leaf
(most probably the problematic function in this case).

Hi Goldwyn,

Could you please verify if the issue could be solved by my recent patch:

[PATCH 1/1] Ocfs2: Add missing ocfs2_journal_acces_*() for couple of 
funcs in dir.c


Thanks,
Tristan.
