Subject: alloc: reduce number of large pages to 256.
X-Git-Url: https://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=bbd7380019f3ea4629d170af24b902bf734c83ea;hp=fbd94d9909892758d594d410bb5f981b3567fb3e

alloc: reduce number of large pages to 256.

This reduces the number of huge allocs, which drops test time from 6 minutes to 57 seconds.
