Subject: [lustre-devel] [PATCH 16/41] lnet: Add the ioctl handler for "add policy"
Date: Sun,  4 Apr 2021 20:50:45 -0400	[thread overview]
Message-ID: <1617583870-32029-17-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1617583870-32029-1-git-send-email-jsimmons@infradead.org>

From: Sonia Sharma <sharmaso@whamcloud.com>

The ioctl handler for "add policy" de-marshals the
udsp rules passed from userspace and then add the
rules if there is no copy of the same rules already
added. Apply the rules to the existing LNet
constructs.

WC-bug-id: https://jira.whamcloud.com/browse/LU-9121
