Subject: [PATCH 1/3] fs/fuse: Remove unneeded kaddr parameter
Date: Tue, 25 May 2021 10:24:26 -0700 [thread overview]
Message-ID: <20210525172428.3634316-2-ira.weiny@intel.com> (raw)
In-Reply-To: <20210525172428.3634316-1-ira.weiny@intel.com>
From: Ira Weiny <ira.weiny@intel.com>
fuse_dax_mem_range_init() does not need the address or the pfn of the
memory requested in dax_direct_access(). It is only calling direct
access to get the number of pages.
Remove the unused variables and stop requesting the kaddr and pfn from
dax_direct_access().
