Subject: block/028: check if T10 verification fails
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=09c0fe1bf86e7a3a23f6e26621ebbe964e7a2c58;p=users%2Fsagi%2Fblktests.git

block/028: check if T10 verification fails

When T10 verification fails, the error code of BLK_STS_PROTECTION
may not be propagated to user space, see mpage_end_io().

So seems the only reliable way for detecting the failure is to
check dmesg.
