> ## ERRORS > > ### 1. Resource leak on error path after lock acquisition The AI review suggested moving the module presence checks inside the lock, which I believe is not necessary. The presence checks occur before acquiring the semaphore, so returning early cannot leak the lock. All error paths after lock acquisition do properly go through the ERROR_IO label and release the semaphore.
I've changed the pre-lock error from -EIO to - EINVAL to better distinguish "module not present" from actual I/O failures. > --- > > ## WARNINGS > > ### 1.
