From cb53a7ee6c6a42a0d8b472eb1d296219def2d877 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 13 May 2013 20:35:38 -0500 Subject: [PATCH] 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.
