[PATCH AUTOSEL 6.6 103/104] net: kcm: fix direct access to bv_len

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mina Almasry <almasrymina@xxxxxxxxxx>

[ Upstream commit b15a4cfe100b9acd097d3ae7052448bd1cdc2a3b ]

Minor fix for kcm: code wanting to access the fields inside an skb
frag should use the skb_frag_*() helpers, instead of accessing the
fields directly.
