Subject: partition iteration simplifications
Date: Tue,  6 Apr 2021 08:22:51 +0200	[thread overview]
Message-ID: <20210406062303.811835-1-hch@lst.de> (raw)

Hi all,

with the switch to an xarray for storing the partitions of a gendisk we
can now use the xarray iterators for iterating over the partitions and don't
really need the disk_part_iter_* scheme.  Also clean up the teardown of
partitions where I think we have a (very unlikely to hit) race currently.
