Subject: [lustre-devel] [PATCH 04/18] lnet: Correct peer NI recovery age out calculation
Date: Mon, 19 Jul 2021 08:31:59 -0400	[thread overview]
Message-ID: <1626697933-6971-5-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1626697933-6971-1-git-send-email-jsimmons@infradead.org>

From: Chris Horn <chris.horn@hpe.com>

The calculation to age a peer NI out of recovery is only valid if
lnet_recovery_limit is non-zero. When set to zero, we allow peer NIs
to be in recovery indefinitely.

HPE-bug-id: LUS-9953
Fixes: b414b1afc8 ("lnet: Age peer NI out of recovery")
WC-bug-id: https://jira.whamcloud.com/browse/LU-14654
Lustre-commit: 8f3f0e1219724d6e ("LU-14654 lnet: Correct peer NI recovery age out calculation")
