Testing with a modified copy of the fsfuzz, the btrfs filesystem hanged with the following output in dmesg. The system still remain responsive, except for the terminal that was doing the testing. Any attempt to list files in the btrfs-mounted directory will block as well. I am not sure how to proceed from here. Possibly to reboot the system next. But anyone can shed some suggestion?

Hi, I tried very promising btrfs to test it a little and I experienced a little bug in implementation. I''m not sure where the bug lies however this works quite well to reproduce the problem: dd if=/dev/zero of=mountme bs=4k count=100000 dd if=/dev/zero of=mountme2 bs=4k count=100000 mkfs.btrfs mountme mkfs.btrfs mountme2 mkdir loop loop2 mount -o loop mountme loop mount -o loop mountme

A few days ago I had a very big problem with tc. On the machine tc is used in many ways: - from crontab to load night-time and day-time bandwidth (at 1am and 8am) - from crontab to get statistics for qdiscs on WAN interfaces (every minute) - from perl/php database for changing user bandwidth (sometimes) What happened: At 1am the night-time bandwidth should be loaded. tc hanged up, and also

Hello everybody, I've my Gentoo's /usr/portage on a loopback btrfs. Just wanted to sync and got an oops. I've a rsync and a ls process in status D now. The system has been in suspend (tuxonice 3.0-rc3) with mounted btrfs, perhaps that is related?

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented. To try the new disk format, you need fresh formatted btrfs.

Hello Developers, it seems that i discovered a bug in btrfs while testing it on a zSeries mainframe :-) ## Test environment: - IBM System z900 Mainframe - Debian SID with 64 Bit Kernel - GIT Sources from git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git - System runs as z/VM guest - 3 Virtual CPUs - 1 GB RAM Storage ## Initial Test Setup - Setup a Debian SID System with

Hi list This happened when running an iozone test over ceph, it was doing lots of random reads. I have no idea how to properly interpret this, I should find it out.

OK - trying to migrate to dovecot and I like what I see so far, but having a hard time getting it to work. I decided to go with the 1.0 version because I need to get away from the ~/Mail namespace. I'm trying to port from a Linuxconf virtual WU-IMAP type config. So - I compiled but then decided I wanted mysql so I tried to reconfigure and now getting compile errors. Looks like I'm

On 3.8-rc2 with lockdep enabled and dual-GPU setup (Macbook Pro Retina), I see two releated lock inversion issues with the EFI framebuffer, leading to possible deadlock: when X takes over from the EFI framebuffer [1] and when nouveau releases the framebuffer when being vgaswitcherood [2]. Let me know if you'd like any testing or analysis when I can get the time. Many thanks, Daniel ---

I would like a command line option to disable this optimization. That way tests can still verify that EVEX instructions came out of isel by using -show-mc-encoding.

Hi All. This is an RFC for a proposed target specific X86 optimization for reducing code size in the encoding of AVX-512 instructions when possible. When the AVX512F instruction set was introduced in X86 it included additional 32 registers of 512bit size each ZMM0 - ZMM31, as well as additional 16 XMM registers XMM16-XMM31 and 16 YMM registers YMM16-YMM31. In order to encode the new registers of

Hal, that’s a good point. There are more manually-maintained tables in the X86 backend that should probably be tablegened: the memory-folding tables and ReplaceableInstrs, to name a couple. If you have ideas on how to get these auto-generated, please let us know.

> I would like a command line option to disable this optimization. That way tests can still verify that EVEX instructions came out of isel by using -show-mc-encoding. I think that keeping tests compatibility is not a reason for an additional “llc” flag. We check encoding in test/MC/X86 dir. Is there any option to report-out from llc in non-debug mode? It should be an option to control

Stamp softlockup thread earlier before do_timer, because the latter is the one to actually trigger lock warning for long-time offline. Or else, I obserevd softlockup warning easily at manual vcpu hot-remove/plug, or when suspend cancel into old context. One point here is to cover both stolen and blocked time to compare with offline threshold. vcpu hotplug falls into ''stolen''
