io_uring: increase IORING_MAX_ENTRIES to 32Kfor-5.4/io_uring-2019-09-15
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. Reported-by: Dan Melnic <dmm@fb.com> Signed-off-by: Daniel Xu <dxu@dxuuu.xyz> Signed-off-by: Jens Axboe <axboe@kernel.dk>
