Subject: [PATCH 09/11] xfs_repair: don't assert if we run across a dir entry with null ino ptr
Date: Tue, 17 Apr 2018 19:47:27 -0700	[thread overview]
Message-ID: <152401964787.13319.7143262291746238151.stgit@magnolia> (raw)
In-Reply-To: <152401958920.13319.10756339531174871801.stgit@magnolia>

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

If we encounter a directory with an entry that points to inode zero,
we'll crash due to an ASSERT during process_inode_chunk.  Instead, just
set the in-core parent to NULLFSINO so that phase 6 will reset it for
us.
