Subject: b=21420 fix aggregate mdt stats
X-Git-Tag: 2.0.56.0~27
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=be69837105edc20cfade1f25e8f3fb5c39b2e216

b=21420 fix aggregate mdt stats

mdt_counter_incr() should act upon obd->md_stats instead of
obd->obd_stats, the former is for recording md ops, while
the later for obd ops.
