Subject: Re: [PATCH] mm/swap: fix wrong plist empty check in swap_alloc_slow()
Date: Thu, 20 Nov 2025 11:06:03 +0900 [thread overview]

I've investigated this further and noticed something about swap_sync_discard.
During iteration, it doesn't perform an empty check on swap devices. As a
result, if the iteration exits because the next device is full
(deleted by plist at this time), the
operation(swap I/O) fails even when other available swap devices remain.
Should this be addressed?
Best Regards,
