The kernel crashes when I try to use "dd" to overwrite a file.
Here's the commands I use on the client in UML:
$ mount -t ceph 172.22.8.14:/ cephfs
$ cd cephfs
$ dd if=/dev/zero of=foo bs=1M count=1024
<successful output from 'dd'>
$ dd if=/dev/zero of=foo bs=1M count=1024
< CRASH! >
It seems that when 'dd' tries to overwrite a file, crash! Below is some
kernel output...
