X-Git-Tag: v3.7-rc1~10^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72f36d5972a166197036c1281963f6863c429bf2;p=pandora-kernel.git md: refine reporting of resync/reshape delays. If 'resync_max' is set to 0 (as is often done when starting a reshape, so the mdadm can remain in control during a sensitive period), and if the reshape request is initially delayed because another array using the same array is resyncing or reshaping etc, when user-space cannot easily tell when the delay changes from being due to a conflicting reshape, to being due to resync_max = 0. So introduce a new state: (curr_resync == 3) to reflect this, make sure it is visible both via /proc/mdstat and via the "sync_completed" sysfs attribute, and ensure that the event transition from one delay state to the other is properly notified.
