From a9f36c3ed48dbfbad4cf8ba92142873b62923300 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 15 Feb 2013 11:42:30 -0600 Subject: [PATCH] libceph: remove dead code in osd_req_encode_op() In osd_req_encode_op() there are a few cases that handle osd opcodes that are never used in the kernel. The presence of this code gives the impression it's correct (which really can't be assumed), and may impose some unnecessary restrictions on some upcoming refactoring of this code. So delete this effectively dead code, and report uses of the previously handled cases as unsupported.
