It first try nowait issue, and offload it to io-wq threads if the first try fails. v2->v3: - removed the kernfs patches - add f_pos_lock logic - remove the "reduce last EOF getdents try" optimization since Dominique reports that doesn't make difference - remove the rewind logic, I think the right way is to introduce lseek to io_uring not to patch this logic to getdents. - add Singed-off-by of Stefan Roesch for patch 1 since checkpatch complained that Co-developed-by someone should be accompanied with Signed-off-by same person, I can remove them if Stefan thinks that's not proper.
