At a stable hardened Gentoo Linux server (kernel 5.1, same for 4.19) I do have
2 BTRFS file systems, ./img1 and ./img2. I do write data to either of it for
about 1 month, then I do switch the symlink ./img from ./img1 to ./img2 or vice
versa.
# grep img /etc/fstab

Will see, if it helps now. But FWIW the mentioned spew happened the first time
here AFAICT.

Within a 32 bit KVM (stable Gentoo) I run into this situation using trinity
(latest git):
tfoerste@n22kvm-clone ~ $ D=/mnt/ramdisk/btrfs; while [[ : ]]; do cd ~; sudo rm
-rf $D/t3 && mkdir $D/t3 || break; cd $D/t3; mkdir -p v1/v2; for i in $(seq 0
99); do touch v1/v2/f$i; mkdir v1/v2/d$i; done;
I do run latest trinity at a 32 bit x86 KVM guest with guest kernel 4.0.ß0-rc5
(host is a 64 bit hardened Gentoo FWIW). Within KVM I prepared a victim file
system via :
$ mkdir /mnt/ramdisk/btrfs; truncate -s 497M /mnt/ramdisk/btrfs.fs;
/sbin/mkfs.btrfs /mnt/ramdisk/btrfs.fs; sudo su -c "mount
Just like to share this :
CC fs/btrfs/print-tree.o

At a 32 bit Gentoo Linux I get with 3.18.5 the following syslog message:

I created within a x86 KVM guest at a tmpfs file system under 3.19.0-rc1 a 257
MB file, created within that abtrfs file system and run the fuzzer trinity
using that fs for its victim files:
$ mkdir /mnt/ramdisk/btrfs; truncate -s 257M /mnt/ramdisk/btrfs.fs;
/sbin/mkfs.btrfs /mnt/ramdisk/btrfs.f
I'm unsure if I already reported this particular issue in detail or not :
As soon as I do start a fuzz testing BTRFS at a 32 bit qemu KVM amachine using
the follwoing commands:
$ mkdir /mnt/ramdisk/btrfs; truncate -s 97M /mnt/ramdisk/btrfs.fs;
/sbin/mkfs.btrfs /mnt/ramdisk/btrfs.fs; sudo su -c

you mean CONFIG_PROVE_LOCKING=y right ?
This is new in my eyes, or ? :

So rather fixed in -rc6 because v3.17-rc4-337-gfc486b0 still s

Ah thx, it seems that fix does not made it in -rc3, so -rc4 wo

So for UML I excluded in the past those 3 syscalls (nowadays no longer
necessary)

Those messages do only appear for a btrfs, not if I choose ext4.
