    Patchset description:
    
    ploop: Allow to resubmit partially completed request
    
    This allows to continue submitting partially completed requests.
    
    https://jira.sw.ru/browse/PSBM-127225
    
    Kirill Tkhai (18):
          ploop: Simplify ploop_write_cluster_sync()
          ploop: Rename hook->pio, h->pio, ploop_cow::hook->aux_pio
          ploop: Rename force_link_inflight_bios
          ploop: Introduce separate lock for inflight pios
          ploop: Use hlist instead of rbtree
          ploop: Always link submitted pios
          ploop: Unexport ploop_inflight_bios_ref_switch()
          ploop: Refactor submit_pio()
          ploop: Introduce ploop_suspend_submitting_pios
          ploop: Refactor ploop_ctr()
          ploop: Use ploop_call_rw_iter() in submit_delta_read()
          ploop: Generalize submit_rw_mapped()
          ploop: Kill submit_delta_read()
          ploop: Rename submit_rw_mapped()
          ploop: Extract submit_rw_mapped() to separate function
          ploop: Save level before submitting pio
          ploop: Make fsync work be able to run in parallel with main work
          ploop: Introduce resubmitting partially completed pios
