Subject: [PATCH] block/blkio: use FUA flag on write zeroes only if supported
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

|
libblkio supports BLKIO_REQ_FUA with write zeros requests only since
|
|
version 1.4.0, so let's inform the block layer that the blkio driver
|
|
supports it only in this case. Otherwise we can have runtime errors
|
|
as reported in https://issues.redhat.com/browse/RHEL-32878
|
|
|
|
Fixes: fd66dbd424 ("blkio: add libblkio block driver")
