static int skd_isr_completion_posted(struct skd_device *skdev,
The SKD_ID_INCR flag in skd_request_context.id duplicates information that is already available otherwise, e.g. through the block layer request state and through skd_request_context.state. Hence remove the code that manipulates this flag and also the flag itself. Since skd_isr_completion_posted() only uses the lower bits of skd_request_context.id as hardware tag, this patch does not change the behavior of the skd driver. I'm referring to the following code: tag = req_id & SKD_ID_SLOT_AND_TABLE_MASK; Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.de> Cc: Johannes Thumshirn <jthumshirn@suse.de> --- drivers/block/skd_main.c | 5 ----- 1 file changed, 5 deletions(-)
