Last year I wrote half a dozen drivers for various USB card readers. Some don't work anymore with 2.5.recent. I just investigated one. The reason it stopped working is the sd_read_cache_type() call added in 2.5.41. (With that call removed it works again.)
Will look a bit more at the details later. For now a question: this call does a MODE_SENSE with the DBD (disable block descriptors) bit set. Is there a reason for that? Wouldn't the same code work in the same way without that bit? And the reason I ask is that we already have sd_do_mode_sense6(), so part of sd_read_cache_type() can be simply replaced by a call of sd_do_mode_sense6(), but the latter needs an extra parameter if DBD is really needed. And a second question: sd_read_cache_type() is called also when no medium is present. Objections against only calling when media are present?
