Subject: io_uring/alloc_cache: shrink default max entries from 512 to 128
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0ae9b9a14d54bd0aa68c1e8bda9dd8e6346f1d87;p=linux.git

io_uring/alloc_cache: shrink default max entries from 512 to 128

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.
