Oops, forgot to say, it is the /tmp/kvm-xfstests-$USER directory on the host (it will be created when you first launch kvm-xfstests and it is "live", i.e. like NFS, not like "pack to ext4 image then boot and mount"). > Hmmm... It doesn't show up on my test system. Mounted it on my host Ubuntu 18.10 amd64, executed `cat /mnt/xyz` and it was "Killed". Maybe it is something freshly added or arch-dependent... # uname -a Linux trosinenko-pc 4.18.0-10-generic #11-Ubuntu SMP Thu Oct 11 15:13:55 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Best regards Anatoly пн, 29 окт. 2018 г. в 6:43, Nicolas Pitre <[email protected]>: > > On Sun, 28 Oct 2018, Anatoly Trosinenko wrote: > > > Hello, > > > > When reading a file from a fuzzed cramfs image, unhandled kernel > > paging request occurs. > > Hmmm...
