Subject: Core: use ngx_palloc_small() to allocate ngx_pool_large_t.
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=9d08bda415b9c987b7a3503bf5fa45cfda15df2e;p=nginx.git

Core: use ngx_palloc_small() to allocate ngx_pool_large_t.

This structure cannot be allocated as a large block anyway, otherwise that will
result in infinite recursion, since each large allocation requires to allocate
another ngx_pool_large_t.

The room for the structure is guaranteed by the NGX_MIN_POOL_SIZE constant.
