Subject: [PATCH 19/21] partitions/msdos: remove LINUX_SWAP_PARTITION
Date: Tue, 24 Mar 2020 08:25:28 +0100 [thread overview]
Message-ID: <20200324072530.544483-20-hch@lst.de> (raw)
In-Reply-To: <20200324072530.544483-1-hch@lst.de>
Just always use NEW_SOLARIS_X86_PARTITION and explain the situation,
as that is less confusing than two names for a single value.
Signed-off-by: Christoph Hellwig <hch@lst.de>
