Subject: sched/wait: fix ___wait_var_event(exclusive)
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cde65194502778665c1b52afc5722cf7dbfaa399;p=linux.git

sched/wait: fix ___wait_var_event(exclusive)

init_wait_var_entry() forgets to initialize wq_entry->flags.

Currently not a problem, we don't have wait_var_event_exclusive().
