Subject: vfs: stop clearing close on exec when closing a fd
X-Git-Tag: v4.19~2150^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5297908270549b734c7c2556745e2385b6d4941d;p=platform%2Fkernel%2Flinux-rpi.git

vfs: stop clearing close on exec when closing a fd

Codepaths allocating a fd always make sure the bit is set/unset
depending on flags, thus clearing on close is redundant.
