[PATCH 16/47] staging/lustre/obdclass: remove uses of lov_stripe_md

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "John L. Hammond" <john.hammond@xxxxxxxxx>

Remove the unused function llog_obd_add(). Remove the unused count and
parameters from llog_cancel(). Move dump_lsm() from obdclass to
the only module that uses it (lov). Remove obd_lov.h.
