Ah, indeed some changes were made at 2.6.18-git9. Goes to show that merely looking at airprime.c from pristine 2.6.18 and then grepping through the git18 patch (looking for 1410) doesn't show you everything... One never ceases to learn.
So anyway, since I'm already here and asking questions: what is the preferred method to perform many small (couple KB) random reads from a USB mass storage device? I can simply read from /dev/sd? or /dev/ub? (don't see much of a difference there, even though ub is supposed to be slower) but that seems to result in very slow access (around 300 reads per second, which seems to be off by a factor of 5 or more).
