Subject: fork: remove redundant TASK_UNINTERRUPTIBLE
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a903904c5fa06e8d8472509741f79e8eb25ff864;p=linux.git

fork: remove redundant TASK_UNINTERRUPTIBLE

TASK_KILLABLE already includes TASK_UNINTERRUPTIBLE, so there is no
need to add a separate TASK_UNINTERRUPTIBLE.
