This is the usual wording for this in net/core

I changed the name of the argument, not its meaning.

$ scripts/kernel-doc net/core/sock.c >/dev/null
Warning(net/core/sock.c:1874): No description found for parameter 'gfp'
Warning(net/core/sock.c:1874): Excess function parameter 'prio'
description in 'skb_page_frag_refill'

Feel free to submit a net-next patch to change net/core occurrences.

Thanks
