fstest generic cases 347 361 628 629 trigger a same issue: When jbd2 enter ABORT status, ocfs2 ignores it and keep going to commit journal. This commit gives ocfs2 ability to handle jbd2 ABORT case.

Sorry, please pause this patch review. When I was investigating fstest generic failed case 347 361, I found the wake_up() action should move out the 'if()' area. The correct way is calling wake_up() unconditionally.

...for your reply. If I add -force-interpreter to lli, then it seems that it can not run external function like printf or malloc. Is there any easy way to solve this problem?

...on in bc file. If this was true, then lli does not have any control to the execution of program. Is this the case? What I was thinking lli would do is fetching each LLVM IR instruction and "execute" it with some tricks. Is there any option for JIT/lli to work like this? -- Regards, Heming Cui -------------- next part -------------- An HTML attachment was scrubbed...

...s YES) In addition, the printf() can work in program, reflecting that libffi is working, right? How can I make Interpreter work with getpid(), fork(), and clone()?

I can reproduce this in my local VM. I've traced ocfs2_dismount_volume and found that it hasn't been called. So EBUSY is returned in VFS layer. I guess something wrong when doing a copy with linked SQEs (normal copy seems no problem). Thanks, Joseph On 2/24/23 8:32 AM, Heming Zhao wrote: > Hello List, > > I found a weird bug on ocfs2.
