Subject: [PATCH 5.4 47/51] xfs: fix uninitialized variable in xfs_attr3_leaf_inactive
Date: Wed,  5 Oct 2022 13:32:35 +0200	[thread overview]
Message-ID: <20221005113212.438169634@linuxfoundation.org> (raw)
In-Reply-To: <20221005113210.255710920@linuxfoundation.org>

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

commit 54027a49938bbee1af62fad191139b14d4ee5cd2 upstream.

Dan Carpenter pointed out that error is uninitialized.  While there
never should be an attr leaf block with zero entries, let's not leave
that logic bomb there.

Fixes: 0bb9d159bd01 ("xfs: streamline xfs_attr3_leaf_inactive")
