From: Kohei Enju Date: Thu, 12 Jun 2025 16:13:40 +0000 (+0900) Subject: igbvf: remove unused interrupt counter fields from struct igbvf_adapter X-Git-Tag: v6.17-rc1~126^2~192^2~1 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ebca2374dbb194a358bdd8a32c1cf9227a7a490;p=thirdparty%2Flinux.git igbvf: remove unused interrupt counter fields from struct igbvf_adapter Remove `int_counter0` and `int_counter1` from struct igbvf_adapter since they are only incremented in interrupt handlers igbvf_intr_msix_rx() and igbvf_msix_other(), but never read or used anywhere in the driver. Note that igbvf_intr_msix_tx() does not have similar counter increments, suggesting that these were likely overlooked during development. Eliminate the fields and their unnecessary accesses in interrupt handlers.
