From: John L. Hammond Date: Sun, 18 Sep 2016 20:38:10 +0000 (-0400) Subject: staging: lustre: obd: remove unused obd methods X-Git-Tag: v4.9-rc1~119^2~432 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=18c33b6b23ef0f7571f7d1d0960fabdd6d2b3b24;p=karo-tx-linux.git staging: lustre: obd: remove unused obd methods Remove no longer used osc_packmd() and osc_getstripe(). Several ioctls cases that are no longer used are removed. Remove no longer used adjust_kms() infrastructure. Signed-off-by: John L.
