Description
In the Linux kernel, the following vulnerability has been resolved:
md/raid1: properly indicate failure when ending a failed write request
This patch addresses a data corruption bug in raid1 arrays using bitmaps.
Without this fix, the bitmap bits for the failed I/O end up being cleared.
Since we are in the failure leg of raid1_end_write_request, the request
either needs to be retried (R1BIO_WriteError) or failed (R1BIO_Degraded).
