Subject: [PATCH] Don't inherit ->splice_pipe across forks
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a0aa7f68afeeb92f6274b395177c20e617c8ed2d;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] Don't inherit ->splice_pipe across forks

It's really task private, so clear that field on fork after copying
task structure.
