History
LOLi c71c8c715b zfs_dbgmsg() is not safe from every context 
This commit reverts to using printk() instead of zfs_dbgmsg() to log
messages in vdev_disk_error(): this is necessary because the latter can
be called from interrupt context where we are not allowed to sleep.
Unfortunately zfs_dbgmsg() performs its allocations calling kmalloc()
with the KM_SLEEP flag which may result in the following oops:
