[PATCH] BLKSIZEGET64 broken in blkpg.c: blk_ioctl()

[Eric Sandeen]

Unless I'm missing something here...

BLKSIZEGET64 is supposed to return device size in bytes, right?

[eric@stout linux]$ grep BLKGETSIZE64 include/linux/fs.h 
#define BLKGETSIZE64 _IOR(0x12,114,sizeof(u64))	/* return device size in bytes (u64 *arg) */

But now it's just returning number of sectors as a u64 number in
blk_ioctl()

So:
