As Jones reported, it is not enough only apply [2] to stable-5.10. Io_uring is very valuable and active module of linux kernel. I've tried to apply these two patches[3] [4] to my local 5.10 code, I found my understanding of io_uring is not enough to resolve all conflicts. Since 5.10 is an important stable branch of linux, we would appreciate your help in soloving this problem.
