| H A D | vdev_geom.c | diff 294027 Thu Jan 14 16:22:11 MST 2016 asomers Fix race condition involving ZFS remove events When a ZFS drive disappears, ZFS sends a resource.fs.zfs.removed event to userland. A userland program like zfsd(8) can use that event, for example to activate a hotspare. The current code contains a race condition: vdev_geom will sent the sysevent _before_ spa.c would update the vdev's status, causing userland processes to see pool state that does not reflect the device removal. This change moves the sysevent to spa.c, closing the race.
