+ num_sectors = size >> curlun->l_blkbits; /* File size in
logic-block-size blocks */
min_sectors = 1;
if (curlun->cdrom) {
num_sectors &= ~3; /* Reduce to a multiple of 2048
*/
And as long as you're using variable logical block sizes, you might as
well set l_blkbits here to 11, because cdroms always use a block size
of 2048.

I've test cdrom as mass storage according to your suggestion:
if (curlun->cdrom)
curlun->l_blkbits = 11;
but it seems that the cdrom doesn't work:
FAT: logical sector size too small for device (logical
sector size = 512)
after set l_blkbits to 9 for cdrom, it works properly.
Shouldn't you be using ISO some-numbers fs (ie. CD-ROM file system) if you
decide
to emulate a CD-ROM?
