From 5f7136db82996089cdfb2939c7664b29e9da141d Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Fri, 29 Jan 2021 04:38:57 +0000 Subject: block: Add bio_max_segs It's often inconvenient to use BIO_MAX_PAGES due to min() requiring the sign to be the same. Introduce bio_max_segs() and change BIO_MAX_PAGES to be unsigned to make it easier for the users.
