+Subject: block: Fix fsync always failed if once failed
+
+From: Ye Bin <yebin10@huawei.com>
+
+commit 8a7518931baa8ea023700987f3db31cb0a80610b upstream.
+
+We do test with inject error fault base on v4.19, after test some time we found
+sync /dev/sda always failed.

+
+As 8d6996630c03 introduce 'fq->rq_status', this data only update when 'flush_rq'
+reference count isn't zero. If flush request once failed and record error code
+in 'fq->rq_status'. If there is no chance to update 'fq->rq_status',then do fsync
+will always failed.
+To address this issue reset 'fq->rq_status' after return error code to upper layer.

+Subject: powerpc/cell: Fix clang -Wimplicit-fallthrough warning
+
+From: Anders Roxell <anders.roxell@linaro.org>
+
+commit e89257e28e844f5d1d39081bb901d9f1183a7705 upstream.
+
+Clang warns:
+
+arch/powerpc/platforms/cell/pervasive.c:81:2: error: unannotated fall-through between switch labels
+ case SRR1_WAKEEE:
+ ^
+arch/powerpc/platforms/cell/pervasive.c:81:2: note: insert 'break;' to avoid fall-through
+ case SRR1_WAKEEE:
+ ^
+ break;
+1 error generated.
+
+Clang is more pedantic than GCC, which does not warn when failing
+through to a case that is just break or return. Clang's version is more
+in line with the kernel's own stance in deprecated.rst. Add athe missing
+break to silence the warning.
