Observed in what will be zfs-0.5.1 when it's tagged.

Observed again in the zfs-0.5.1 tag while running the zfault tests under FC13, 2.6.34.6-47.fc13.x86_64. It's still rare.

This is believed to be fixed by the cv changes in the zfs range locking code.

Allow perf record command to be specified in env (openzfs#47)
96c1168 
On 5.11 kernels, the `--call-graph dwarf,8192` option to perf causes
it to crash. This change allows callers to specify a different perf
invocation via the PERF_RECORD_CMD environment variable.
