Subject: linux-next: build warning after merge of the scsi tree
Date: Thu, 6 Apr 2017 14:04:55 +1000
Message-ID: <20170406140455.0ee0058f@canb.auug.org.au> (raw)

Hi James,

After merging the scsi tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from include/linux/list.h:8:0,
                 from include/linux/module.h:9,
                 from drivers/scsi/sd.c:35:
drivers/scsi/sd.c: In function 'sd_revalidate_disk':
include/linux/kernel.h:755:16: warning: comparison of distinct pointer types lacks a cast
  (void) (&min1 == &min2);   \
                ^
include/linux/kernel.h:758:2: note: in expansion of macro '__min'
  __min(typeof(x), typeof(y),   \
  ^
include/linux/kernel.h:783:39: note: in expansion of macro 'min'
  __x == 0 ? __y : ((__y == 0) ? __x : min(__x, __y)); })
                                       ^
drivers/scsi/sd.c:2959:12: note: in expansion of macro 'min_not_zero'
   rw_max = min_not_zero(logical_to_sectors(sdp, dev_max),
            ^

Introduced by commit

  c3e62673ee20 ("scsi: sd: Consider max_xfer_blocks if opt_xfer_blocks is unusable")

logical_to_sectors() is a sector_t and BLK_DEF_MAX_SECTORS is an "enum
blk_default_limits" (i.e. int).
