From 406e2c9f9286fc93ae2191a7abf477dea05aadc9 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 15 Apr 2013 14:50:36 -0500 Subject: libceph: kill off osd data write_request parameters In the incremental move toward supporting distinct data items in an osd request some of the functions had "write_request" parameters to indicate, basically, whether the data belonged to in_data or the out_data. Now that we maintain the data fields in the op structure there is no need to indicate the direction, so get rid of the "write_request" parameters.
