It is not safe to use the task_struct returned by kthread_run(threadfn)

fDeviceInit query response time for some devices is too long that default
query request timeout of 100ms may not be enough. Experiments show that
fDeviceInit response sometimes takes 500ms so to be on safer side this
change sets the timeout to 600ms. Without this change, we might
unnecessarily have
Some of the data structures (like response UPIU) and/or its elements
(unused fields) should be cleared before sending out the respective
command to UFS device.
This change clears the UPIU response data structure for query commands
and NOP command before sending out the command. We also initialize
Clear the UFS data structures before sending new request.
The SCSI command is sent to the device within the UFS UPIU request.
As part of the transfer UPIU preparation, the SCSI command is copied
to the UPIU structure according to the SCSI command size.
As different SCSI commands differ in size fro

We currently don't support storing multiple session in perf.data,
so we can't allow -r option in stat record.
$ perf stat -e cycles -r 2 record ls

Applied to for-next, thanks!
In the future, when
Add 'perf stat record' command support. It creates simple
