[f2fs-dev] [PATCH 1/2] workqueue: add io priority to work_struct

Many works will go to submit_bio(), and in many cases the io priority of kworker cannot meet the real-time requirements of this work. So add the basic attribute ioprio to work_struct, and kworker can adjust its io priority according to this attribute. Add function set_work_ioprio() to set the io

[f2fs-dev] [PATCH 0/2] add io priority feature to work and use it in f2fs fsverity work

Many works will go to submit_bio(). In many cases, the default io priority of kworker cannot meet the real-time requirements of the work. Such as f2fs_verify_bio work. If a high-task-priority process reads the verity-file, it is likely that the high-task-priority process will be slowly because the

[f2fs-dev] [PATCH 2/2] f2fs: set f2fs verify work io priority

The io priority of reading the original data of the verity-file and reading hash blocks during verification should be consistent. If the io priority is not set, when a high-task-priority process reads the verity-file, the kworker's io priority may be too low, resulting in delayed reading of hash bl
