Hi!
Today one of my computers crashed with the following panic.
The machine is heavily using reflinks.
Looks like it managed to hit a CATCH_BH_JBD_RACES error check.

Hello,
It seems like Sunil has fixed a similar issue against ocfs2-1.4
several years ago:
https://oss.oracle.com/git/?p=ocfs2-1.4.git;a=commitdiff_plain;h=2fd250839d0f5073af8d42e97f1db74beb621674;hp=e882faf84930431524f84598caea7d4e9a9529c5
https://oss.oracle.com/git/?p=ocfs2-1.4.git;a=commitdiff_plain;h=eccff85213d4c2762f787d9e7cb1503042ba75b9;hp=edc147473ffd9c03790dc4502b893823f44a9ec4
The old bug ticket for the discussion:
https://oss.oracle.com/bugzilla/show_bug.cgi?id=1235
This fix is specifically for ocfs2-1.4, but Mark once mentioned that
the BUG() there can be removed if we have a good explanation for this
sort of behavior, is it time to have it in mainline?
Thanks,
-Jeff

Hmm, not fun.
In my case I'm not using NFS or any other network filesystem.
The OCFS2 is also used in local mode (no cluster).
What really worries me is that this another proof that Oracles OCFS2 branch is out of sync with mainline.
- Are there more fixes pending?
- Why aren't you pushing things back to mainline?

It seems that this problem is irrelevant to cluster/network mode.
Any test case can help reproducing this problem if possible.

Andrew help us merging OCFS2 mainlines fixes, you can fetch the updated
from his tree.

Sure. That depends on how many fixes have been posted and how many person
are got involved in the patch review over a period of time.

Because am not dedicated developer for OCFS2, although it spent me some time
to take care of OCFS2 issues recently.

https://oss.oracle.com/git/?p=ocfs2-1.4.git seems to contain fixes for years
which are not mainline.

Ok just FYI I don't believe that to actually be the case - there might be
one or two fixes that were changed when ported to mainline and
there's certainly the possiblity that a mistake was made. But generally
fixes went from mainline into the 1.4 repository and not the other way.
That's not to say things haven't been slow on the Ocfs2 front lately or
anything, but I don't believe it to be the case that fixees are regularly
being put into an Oracle tree that haven't seen mainline.
