Subject: [PATCH] libhandle: zap fdhash_head in fshandle_destroy
Date: Wed, 6 Dec 2017 09:54:01 -0800	[thread overview]
Message-ID: <20171206175401.GK19219@magnolia> (raw)

From: Darrick J. Wong <darrick.wong@oracle.com>

Set fdhash_head to zero once we've destroyed the handle list to avoid
dangling pointer problems.
