Subject: [PATCH 01/15] xfs: don't clear the "dinode core" in xfs_inode_alloc
Date: Sat, 20 Jun 2020 09:10:48 +0200 [thread overview]
Message-ID: <20200620071102.462554-2-hch@lst.de> (raw)
In-Reply-To: <20200620071102.462554-1-hch@lst.de>
The xfs_icdinode structure just contains a random mix of inode field,
which are all read from the on-disk inode and mostly not looked at
before reading the inode or initializing a new inode cluster. The
only exceptions are the forkoff and blocks field, which are used
in sanity checks for freshly allocated inodes.
