#     io_uring/io-wq: don't clear PF_IO_WORKER on exit
#     
#     A recent commit gated the core dumping task exit logic on current->flags
#     remaining consistent in terms of PF_{IO,USER}_WORKER at task exit time.
#     This exposed a problem with the io-wq handling of that, which explicitly
#     clears PF_IO_WORKER before calling do_exit().
#     
#     The reasons for this manual clear of PF_IO_WORKER is historical, where
#     io-wq used to potentially trigger a sleep on exit. As the io-wq thread
#     is exiting, it should not participate any further accounting. But these
#     days we don't need to rely on current->flags anymore, so we can safely
#     remove the PF_IO_WORKER clearing.
