Subject: [PATCH v8 bpf-next 4/9] net/wireless/iwlwifi: fix iwlwifi_dev_ucode_error tracepoint
Date: Wed, 28 Mar 2018 12:05:35 -0700	[thread overview]
Message-ID: <20180328190540.370956-5-ast@kernel.org> (raw)
In-Reply-To: <20180328190540.370956-1-ast@kernel.org>

fix iwlwifi_dev_ucode_error tracepoint to pass pointer to a table
instead of all 17 arguments by value.
dvm/main.c and mvm/utils.c have 'struct iwl_error_event_table'
defined with very similar yet subtly different fields and offsets.
tracepoint is still common and using definition of 'struct iwl_error_event_table'
from dvm/commands.h while copying fields.
Long term this tracepoint probably should be split into two.
