Subject: [PATCH 5.4 CANDIDATE 02/17] xfs: merge the projid fields in struct xfs_icdinode
Date: Tue, 11 Apr 2023 09:04:59 +0530	[thread overview]
Message-ID: <20230411033514.58024-3-chandan.babu@oracle.com> (raw)
In-Reply-To: <20230411033514.58024-1-chandan.babu@oracle.com>

From: Christoph Hellwig <hch@lst.de>

commit de7a866fd41b227b0aa6e9cbeb0dae221c12f542 upstream.

There is no point in splitting the fields like this in an purely
in-memory structure.
