Subject: [PATCH v5 07/10] dax: Fix alloc_dax_region() compile warning
Date: Thu, 29 Aug 2019 18:52:54 -0700	[thread overview]
Message-ID: <156712997439.1616117.16528244368706387135.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <156712993795.1616117.3781864460118989466.stgit@dwillia2-desk3.amr.corp.intel.com>

PFN flags are (unsigned long long), fix the alloc_dax_region() calling
convention to fix warnings of the form:

>> include/linux/pfn_t.h:18:17: warning: large integer implicitly truncated to unsigned type [-Woverflow]
    #define PFN_DEV (1ULL << (BITS_PER_LONG_LONG - 3))
