From da22bdf38be2f2ba557d3031108614ebbba265e1 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 21 Mar 2024 07:53:07 -0600 Subject: [PATCH] io_uring/poll: shrink alloc cache size to 32 This should be plenty, rather than the default of 128, and matches what we have on the rsrc and futex side as well.
