Let me put it more plainly. Martin Daleki + rumour assures me that the blk_size array nowadays measure in blocks not KB, yet to me it seems that it doesn't. Look at this code from ll_rw_blk.c in 2.4.13:
unsigned long maxsector = (blk_size[major][MINOR(bh->b_rdev)] << 1) + 1;
and this comment:
* blk_size contains the size of all block-devices in units of 1024 * byte sectors:
so blk_size measures in KB. Where do I see it wrong? Is everybody talking about 2.4.14 and 2.4.15? No .. it's just the same in 2.4.14:
if (blk_size[major]) minorsize = blk_size[major][MINOR(bh->b_rdev)]; if (minorsize) { unsigned long maxsector = (minorsize << 1) + 1;
KB! Or is it the case that sectors don't mean 512B?
