NAME

       blk_queue_invalidate_tags - invalidate all pending tags

SYNOPSIS

       void blk_queue_invalidate_tags  (request_queue_t * q);

ARGUMENTS

       q      the request queue for the device

DESCRIPTION

       Hardware conditions may dictate a need to stop all pending requests. In
       this case, we will safely clear the block side of  the  tag  queue  and
       readd all requests to the request queue in the right order.

NOTES

       queue lock must be held.
