Subject: mds: mark beacons as high priority
X-Git-Tag: v13.2.2~76^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=536e6489a8f393d32339f04e8e7382f6ff150aeb;p=ceph.git

mds: mark beacons as high priority

The mons already mark beacon replies as high priority (via default mon message
priority). We should expect that the mons handle our beacons at the same
priority so the MDS doesn't wrongly get marked laggy.

Fixes: http://tracker.ceph.com/issues/26899
