From: Daniel Xu <dxu@dxuuu.xyz> mainline inclusion from mainline-5.4-rc1 commit 5277deaab9f98229bdfb8d1e30019b6c25052708 category: feature bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=27 CVE: NA --------------------------- Some workloads can require far more than 4K oustanding entries. For example memcached can have ~300K sockets over ~40 cores. Bumping the max to 32K seems to work pretty well.
