Wu Fengguang ff8b16d7e1 vmstat: fix offset calculation on void* ... Fix regression introduced by commit 79da826aee ("writeback: report dirty thresholds in /proc/vmstat"). The incorrect pointer arithmetic can result in problems like this: BUG: unable to handle kernel paging request at 07c06d16 IP: [<c050c336>] strnlen+0x6/0x20 Call Trace: [<c050a249>] ? string+0x39/0xe0 [<c042be6b>] ? __wake_up_common+0x4b/0x80 [<c050afcc>] ? vsnprintf+0x1ec/0x380 [<c04b380e>] ? seq_printf+0x2e/0x60 [<c04829a6>] ? vmstat_show+0x26/0x30 [<c04b3bb6>] ? seq_read+0xa6/0x380 [<c04b3b10>] ? seq_read+0x0/0x380 [<c04d5d2f>] ? proc_reg_read+0x5f/0x90 [<c049c4a1>] ? vfs_read+0xa1/0x140 [<c04d5cd0>] ? proc_reg_read+0x0/0x90 [<c049c981>] ? sys_read+0x41/0x70 [<c0402bd0>] ? sysenter_do_call+0x12/0x26 Reported-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: Michael Rubin <mrubin@google.com> Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2010-11-03 14:39:58 -04:00
