.SH "NAME"

.SH "SYNOPSIS"
.HP \w'void\ blk_set_runtime_active('u
.BI "void blk_set_runtime_active(struct\ request_queue\ *\ " "q" ");"
.SH "ARGUMENTS"

the queue of the device

.SH "DESCRIPTION"
.PP
If the device is left runtime suspended during system suspend the resume hook typically resumes the device and corrects runtime status accordingly\&. However, that does not affect the queue runtime PM status which is still
\(lqsuspended\(rq\&. This prevents processing requests from the queue\&.
.PP
This function can be used in driver\*(Aqs resume hook to correct queue runtime PM status and re\-enable peeking requests from the queue\&. It should be called before first request is added to the queue\&.
