Re: [f2fs-dev] Userspace locks at f2fs_issue_flush kernel call, hard reset necessary

Hello Chao, I was holding for a while and taking care of other things, but now since I upgraded to kernel v4.13 (in fact I jumped to 4.13.3), I seem to be no longer affected by this problem. My system has been running fine for over two weeks. I appreciate your help in this matter. Should I

Hi, no problem at all. No, I never did ro remount before it happened. In fact its been a long while since I used ro. Regards On Thu, Aug 31, 2017 at 8:01 AM, Chao Yu wrote: > Hi Marcelo, > > Sorry for the delay, :( > > I'd like ask, any possible that we did ro remount

Hi Marcelo, Sorry for the delay, :( I'd like ask, any possible that we did ro remount before the problem happened? Thanks, On 2017/8/24 1:26, Marcelo "Marc" Ranolfi wrote: > Chao, > > I just had the same problem, with kernel 4.12.8 with patch _f2fs: fix > out-of-order execution in

Re: [f2fs-dev] Userspace locks at f2fs_issue_flush kernel call, hard reset necessary

Hi, as an update, I've been able to reproduce this bug reliably by using a lot of RAM in order to force swap (I have vm_swappiness at 10). Once swapping takes place, it's only a matter of time until some userspace application locks at f2fs_issue_flush. It will remain locked even when I free

Re: [f2fs-dev] Userspace locks at f2fs_issue_flush kernel call, hard reset necessary

Chao, I just had the same problem, with kernel 4.12.8 with patch _f2fs: fix out-of-order execution in f2fs_issue_flush_. On Tue, Aug 22, 2017 at 2:00 PM, Marcelo "Marc" Ranolfi wrote: > Hi Chao > > I'm testing the kernel with your patch since last night. Will give new >

Hi Chao I'm testing the kernel with your patch since last night. Will give new feedback a couple of days/weeks about how it goes. Thank you. On Mon, Aug 21, 2017 at 11:58 AM, Chao Yu wrote: > Hi Marcelo, > > Thanks for the report! > > Would you have a try with below patch?

Re: [f2fs-dev] Userspace locks at f2fs_issue_flush kernel call, hard reset necessary

Hi Marcelo, Thanks for the report! Would you have a try with below patch? f2fs: fix out-of-order execution in f2fs_issue_flush Thanks, On 2017/8/16 15:24, Marcelo "Marc" Ranolfi wrote: > Just wanted to let you all know that this is still an issue, even with > the 4.12.7 kernel. > > The two

Re: [f2fs-dev] Userspace locks at f2fs_issue_flush kernel call, hard reset necessary

Just wanted to let you all know that this is still an issue, even with the 4.12.7 kernel. The two most affected applications are qemu-system-x86_64 and totem. On Wed, Aug 9, 2017 at 3:04 AM, Marcelo "Marc" Ranolfi wrote: > What follows is a bug report. > > I've been
