Summary
md/raid1,raid10: fix error-path detection with md_cloned_bio()
Details

In the Linux kernel, the following vulnerability has been resolved:

md/raid1,raid10: fix error-path detection with md_cloned_bio()

Detect the error path using md_cloned_bio() instead of relying on r1_bio in raid1 or r10_bio->read_slot in raid10, which may be NULL or -1 after splitting and resubmitting a failed bio.

As a result, the error path may not be recognized and memory allocations can incorrectly use GFP_NOIO instead of (GFP_NOIO | __GFP_HIGH), which can lead to a deadlock under memory pressure.
