Subject: rbd: move stripe_unit and stripe_count into header
X-Git-Tag: accepted/tizen/common/20141203.182822~2012^2~91
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=500d0c0fbb85b59e5e75fc83ff701b7d8aa285f9;p=platform%2Fkernel%2Flinux-arm64.git

rbd: move stripe_unit and stripe_count into header

This commit added fetching if fancy striping parameters:
    09186ddb rbd: get and check striping parameters

They are almost unused, but the two fields storing the information
really belonged in the rbd_image_header structure.

This patch moves them there.
