Subject: [PATCH 15/16] xfs: move the block format conversion out of line in xfs_dir2_sf_addname
Date: Tue, 30 Apr 2024 14:49:25 +0200	[thread overview]
Message-ID: <20240430124926.1775355-16-hch@lst.de> (raw)
In-Reply-To: <20240430124926.1775355-1-hch@lst.de>

Move the code to convert to the block format and add the entry to the end
of xfs_dir2_sf_addname instead of the current very hard to read compound
statement in the middle of the function.
