Subject: lwp: Drop inappropriate oops in lwpSigWait()
X-Git-Tag: v4.4.1~72
X-Git-Url: http://git.pond.sub.org/?p=empserver;a=commitdiff_plain;h=2c12238ecb29888c2059378757a97c85af195b19

lwp: Drop inappropriate oops in lwpSigWait()

lwpSigWait()'s contract specifies failure, which means oopsing is
wrong.  Harmless, as its only caller empth_wait_for_signal() oopses on
failure.  Drop it anyway.
