Subject: tasks/exit: Remove unused task_is_dead() method
X-Git-Tag: v4.14-rc1~8264^2~57
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=86506a99a62400e9f7b7d1344bcc9ea235faf98f;p=platform%2Fkernel%2Flinux-rpi.git

tasks/exit: Remove unused task_is_dead() method

task_is_dead() has no users since commit 43e13cc107cf
("cred: remove task_is_dead() from __task_cred() validation"), and
nobody except exit.c should rely on ->exit_state (we still have
the users which should be changed).
