* WQ_MEM_RECLAIM for the scrub thread does not seem right
I think scrub_workers,scrub_wr_completion_workers still need WQ_MEM_RECLAIM.
However scrub_nocow_workers does not need WQ_MEM_RECLAIM flags.
Did you mean this?
If you didn't mean this, would you please tell me why the WQ_MEM_RECLAIM is
not
needed?
Documentation says that threads that might be used in the memory reclaim
path must use this flag, but I don't see how this applies to scrub
threads. They're not writing out dirty data, though they may issue a
write, but that's not their main purpose.
Thanks for your explain.
I understand now, and will remove the WQ_MEM_RECLAIM flagsin the recent
V3 patches.
