Description

In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix leak of &#39;r10bio->remaining&#39; for recovery raid10_sync_request() will add &#39;r10bio->remaining&#39; for both rdev and replacement rdev. However, if the read io fails, recovery_request_write() returns without issuing the write io, in this case, end_sync_request() is only called once and &#39;remaining&#39; is leaked, cause an io hang. Fix the problem by decreasing &#39;remaining&#39; according to if &#39;bio&#39; and &#39;repl_bio&#39; is valid.
