From 069fc464f1e80df06d156ef606cebc61ee00b63e Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 17 May 2022 23:40:45 -0400 Subject: [PATCH] block: Use PAGE_SECTORS_SHIFT The bare use of '9' confuses some people. We also don't need this cast, since the compiler does exactly that cast for us.
