Subject: security: bpf: replace include of linux/bpf.h with forward declarations
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1495dc9f0a711a54f8fec849ce7f3a8f585a11e5;p=openwrt%2Fstaging%2Fblogic.git

security: bpf: replace include of linux/bpf.h with forward declarations

Touching linux/bpf.h makes us rebuild a surprisingly large
portion of the kernel.  Remove the unnecessary dependency
from security.h, it only needs forward declarations.
