Subject: [lustre-devel] [PATCH 15/42] lnet: Conditionally attach rspt in LNetPut & LNetGet
Date: Mon,  5 Oct 2020 20:05:54 -0400	[thread overview]
Message-ID: <1601942781-24950-16-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1601942781-24950-1-git-send-email-jsimmons@infradead.org>

From: Chris Horn <hornc@cray.com>

Create a function to interpret the message type and md options to
determine whether response tracking should be enabled for a particular
PUT or GET.

Use that function in LNetPut and LNetGet to determine whether we
attach the response tracker.
