| |
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).
-- Cheers, Stephen Rothwell
