Subject: xfs: convey metadata health events to the health monitor
X-Git-Tag: v7.0.0~92
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=207a7d1e6b7c7dea212b60734dbeda2f202199e7;p=xfsprogs-dev.git

xfs: convey metadata health events to the health monitor

Source kernel commit: 5eb4cb18e445d09f64ef4b7c8fdc3b2296cb0702

Connect the filesystem metadata health event collection system to the
health monitor so that xfs can send events to xfs_healer as it collects
information.
