Subject: [dm-devel] add a bvec_virt helper
Date: Wed,  4 Aug 2021 11:56:19 +0200	[thread overview]
Message-ID: <20210804095634.460779-1-hch@lst.de> (raw)

Hi Jens,

this series adds a bvec_virt helper to return the virtual address of the
data in bvec to replace the open coded calculation, and as a reminder
that generall bio/bvec data can be in high memory unless it is caller
controller or in an architecture specific driver where highmem is
impossible.
