devfs_data_transfer checks for other tasks block on the same device

Open tyler-gilbert opened this issue 7 years ago • 0 comments

Other tasks should never be blocked on the same device. If another task tries to read/write a device that is busy, an EBUSY error will be returned.

Is there any case where two tasks can be blocked on the same device?
