At as 32 bit KVM I run these 2 commands:
tfoerste@n22kvm ~ $ mkdir /mnt/ramdisk/btrfs; truncate -s 97M /mnt/ramdisk/btrfs.fs; /sbin/mkfs.btrfs /mnt/ramdisk/btrfs.fs; sudo su -c "mount -o loop,compress=lzo /mnt/ramdisk/btrfs.fs /mnt/ramdisk/btrfs; chmod 777 /mnt/ramdisk/btrfs"
tfoerste@n22kvm ~ $ 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; trinity -C 4 -N 100000 -V $D/t3/v1/v2; echo; echo " done"; echo; sleep 4; done
After a short while the syslog was flooded with :

I believe that this warning of btrfs_evict_inode also comes from a result of
lseek, and Chris said that he's prepared a fix for that, so it's queued in the
next version.

Ah thx, it seems that fix does not made it in -rc3, so -rc4 would be a better choice for a re-test, or ?

So rather fixed in -rc6 because v3.17-rc4-337-gfc486b0 still suffers from this issue ?
