Subject: HTTP/2: lingering close changed to handle NGX_AGAIN.
X-Git-Tag: release-1.19.7~10
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=327e21c43293ecfdbd116bd572ee08b7d8066b24;p=nginx.git

HTTP/2: lingering close changed to handle NGX_AGAIN.

This part somehow slipped away from c5840ca2063d.

While it is not expected to be needed in case of lingering close,
it is good to keep it for correctness (see 2b5528023f6b).
