Hibernate and resume process submits individual IO requests for each page of the data, so use blk_plug to improve the batching of these requests. Testing this change with hibernate and resumes consistently shows merging of the IO requests and more than an order of magnitude improvement in hibernate and resume speed is observed. One hibernate and resume cycle for 16GB RAM out of 32GB in use takes around 21 minutes before the change, and 1 minutes after the change on a system with limited storage IOPS.
