From ad3ab8b608c454f004391bb8568916bd955001ea Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Thu, 29 Jan 2015 12:38:29 -0500 Subject: md: do_release_stripe(): No need to call md_wakeup_thread() twice 67f455486d2ea20b2d94d6adf5b9b783d079e321 introduced a call to md_wakeup_thread() when adding to the delayed_list. However the md thread is woken up unconditionally just below. Remove the unnecessary wakeup call.
