RH-Commit: [1/2] 0d9ec74bf3bb999c8baa929e0d25682680fa1731 (kmwolf/rhel-qemu-kvm)
|
|
|
|
While the kernel side isn't merged yet and we're still using old kernel
|
|
headers, just define DM_MPATH_PROBE_PATHS manually.
|
|
|
|
This is a downstream-only patch that can be removed after the next minor
|
|
release.
