Subject: [md:for-next 32/33] drivers/md/raid5.c:2866:3: warning: format '%lu' expects argument of type 'long
Date: Wed, 26 Sep 2012 01:39:08 +0000	[thread overview]
Message-ID: <20120926013908.GE8522@localhost> (raw)

Hi Alexander,

FYI, there are new compile warnings show up in

tree:   git://neil.brown.name/md for-next
head:   0179d361662367ab0f80b5822b162a1c0ba9b57d
commit: eadb9fb1d4da32ed1b143a6fc1997c4c42ea0422 [32/33] md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write.
config: m68k-allyesconfig

All warnings:

drivers/md/raid5.c: In function 'handle_stripe_dirtying':
drivers/md/raid5.c:2866:3: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'sector_t' [-Wformat]

vim +2866 drivers/md/raid5.c

  2853		 * Otherwise, check whether resync is now happening or should start.
  2854		 * If yes, then the array is dirty (after unclean shutdown or
  2855		 * initial creation), so parity in some stripes might be inconsistent.
  2856		 * In this case, we need to always do reconstruct-write, to ensure
  2857		 * that in case of drive failure or read-error correction, we
  2858		 * generate correct data from the parity.
