Abstract
An abort function for storage devices sets a 'poison bit' flag in the command to be deleted while the command resides on a submission queue prior to being fetched by the SSD controller. In response to the set 'poison bit' flag, a storage device controller aborts execution of the I/O command and returns an abort successful status reply to the completion queue.
