Subject: [NETPOLL]: rx_flags bugfix
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11513128bb66b0b09d5d0df069b58afdb01752a2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[NETPOLL]: rx_flags bugfix

Initialize npinfo->rx_flags.  The way it stands now, this will have random
garbage, and so will incur a locking penalty even when an rx_hook isn't
registered and we are not active in the netpoll polling code.
