Subject: net: bpf: fix bpf syscall dependence on anon_inodes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=38b3629adb8c048dda8b98e888505c79ed33ae92;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net: bpf: fix bpf syscall dependence on anon_inodes

minimal configurations where EPOLL, PERF_EVENTS, etc are disabled,
but NET is enabled, are failing to build with link error:
kernel/built-in.o: In function `bpf_prog_load':
syscall.c:(.text+0x3b728): undefined reference to `anon_inode_getfd'

fix it by selecting ANON_INODES when NET is enabled

 	  Unless you really know what you are doing, you should say Y here.
 	  The reason is that some programs need kernel networking support even
