usb_disk's B_GET_GEOMETRY properly sets the read_only flag. So is this still an issue? Can someone retest? I don't know if I have any USB sticks with a write lock around here...
Note:
See TracTickets
for help on using tickets.
Assuming usb_disk is the underlying driver, usb_disk_open() doesn't have any handling for the open mode (
flags). I don't think I've seen any driver that does, though.
