MD: Remember the last sync operation that was performed
MD: Remember the last sync operation that was performed This patch adds a field to the mddev structure to track the last sync operation that was performed. This is especially useful when it comes to what is recorded in mismatch_cnt in sysfs. If the last operation was "data-check", then it reports the number of descrepancies found by the user-initiated check. If it was a "repair" operation, then it is reporting the number of descrepancies repaired. etc. Signed-off-by: NJonathan Brassow <jbrassow@redhat.com> Signed-off-by: NNeilBrown <neilb@suse.de>
