Оригинално описание
In the Linux kernel, the following vulnerability has been resolved: md/raid1: free r1_bio when REQ_NOWAIT is set and read would block on retry When a read is retried, raid1_read_request() may be called with a pre-allocated r1_bio. If wait_read_barrier() fails for a REQ_NOWAIT read, the bio is completed and the function returns immediately. In this case the existing r1_bio is leaked. This fixes a leak of pre-allocated r1_bio structures for retried reads.
