From: Alex Elder Date: Tue, 14 May 2013 01:35:38 +0000 (-0500) Subject: rbd: drop original request earlier for existence check X-Git-Tag: v3.12-rc2~16^2~81 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=912c317d4600b81664ad8f3d3ba6c1f2ff4b49c2;p=kernel%2Fkernel-generic.git rbd: drop original request earlier for existence check The reference to the original request dropped at the end of rbd_img_obj_exists_callback() corresponds to the reference taken in rbd_img_obj_exists_submit() to account for the stat request referring to it. Move the put of that reference up right after clearing that pointer to make its purpose more obvious.
