Subject: tests: Gate tests for linear flavor with variable LINEAR
X-Git-Tag: mdadm-4.3~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=64a4fcb4c2b91d18955752e76517dee2d17b1647;p=thirdparty%2Fmdadm.git

tests: Gate tests for linear flavor with variable LINEAR

linear flavor is being removed in the kernel [1], so tests for the linear
flavor will fail. Add detection for linear flavor and --disable-linear
option, with the same logic as multipath.
