[PATCH] fix BLKTRACESETUP32 compile error

From: FUJITA Tomonori
Date: Thu Jul 08 2010 - 19:59:55 EST


I got the following compile error with block's for-2.6.36 tree:

block/compat_ioctl.c: In function compat_blkdev_ioctl:
block/compat_ioctl.c:754: error: BLKTRACESETUP32 undeclared (first use in this function)
block/compat_ioctl.c:754: error: (Each undeclared identifier is reported only once
block/compat_ioctl.c:754: error: for each function it appears in.)


This is due to "block: push BKL into blktrace ioctls" patch.

Subject: [PATCH] fix BLKTRACESETUP32 compile error

We need BLKTRACESETUP32 even with CONFIG_BLK_DEV_IO_TRACE disabled.
