Message-Id: <20180406084344.988385539@linuxfoundation.org> Date: Fri, 6 Apr 2018 15:24:55 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Mikulas Patocka <mpatocka@...hat.com>, Jens Axboe <axboe@...nel.dk> Subject: [PATCH 4.16 30/31] Fix slab name "biovec-(1<<(21-12))" 4.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mikulas Patocka <mpatocka@...hat.com> commit bd5c4facf59648581d2f1692dad7b107bf429954 upstream. I'm getting a slab named "biovec-(1<<(21-12))". It is caused by unintended expansion of the macro BIO_MAX_PAGES. This patch renames it to biovec-max.
