Subject: [PATCH] io_uring/alloc_cache: shrink default max entries from 512 to 128
Date: Tue, 19 Mar 2024 17:37:43 -0600 [thread overview]
Message-ID: <72a3ccac-b97c-4e62-acd7-dc4f306eba50@kernel.dk> (raw)
In practice, we just need to recycle a few elements for (by far) most
use cases. Shrink the total size down from 512 to 128, which should be
more than plenty.
