Subject: dm-integrity: always set the io hints
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cbc1532d2b0ec2a842bd459f01b590bbf16b7443;p=thirdparty%2Fkernel%2Fstable.git

dm-integrity: always set the io hints

Don't depend on the defaults to be what is desired if the integrity
device was set up with 512b sector size. Always set the queue limits to
be at least what the device mapper wants.
