Subject: [lustre-devel] [PATCH 05/29] lnet: socklnd: remove tcp bonding
Date: Sun, 25 Apr 2021 16:08:12 -0400	[thread overview]
Message-ID: <1619381316-7719-6-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1619381316-7719-1-git-send-email-jsimmons@infradead.org>

From: Serguei Smirnov <ssmirnov@whamcloud.com>

TCP bonding in the socklnd has become obsolete with LNet
Multi-Rail and there's no evidence it's being used anywhere.
Remove it to keep the code simple.

WC-bug-id: https://jira.whamcloud.com/browse/LU-13641
Lustre-commit: d123c47a18adbf56 ("LU-13641 socklnd: remove tcp bonding")
