In the Linux kernel, the following vulnerability has been resolved:
dm-io: report non-retryable errors separatedly
The error codes BLK STS NOTSUPP and BLK STS INVAL should not cause leg
failure on dm-raid1. This patch changes the interface to dm-io, so that
it reports two error bitmaps - error bits and unsup bits. The unsup bit
bitmap tracks BLK STS NOTSUPP or BLK STS INVAL errors, the error bits
bitmap tracks all the other errors.
dm-raid1 is changed so that it won't fail a leg if it receives an error
in the unsup bits bitmap.
This patch (with 62dc37a819a5) fixes misbehavior if the user uses
unaligned bio vectors on dm-raid1.
