commit 661061a45e32d8b2cc0e306da9f169ad44011382
bugzilla: 51867
CVE: NA

--------------------------------

commit 2417b986 upstream.

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).

Fixes: eeba6809 ("md/raid1: end bio when the device faulty")
