From b84cd05098275a7625223141d019f8af5a17323b Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 8 Nov 2024 13:53:27 +1100 Subject: log: Only check for FALLOC_FL_COLLAPSE_RANGE availability at runtime log.c has several #ifdefs on FALLOC_FL_COLLAPSE_RANGE that won't attempt to use it if not defined. But even if the value is defined at compile time, it might not be available in the runtime kernel, so we need to check for errors from a fallocate() call and fall back to other methods. Simplify this to only need the runtime check by using linux_dep.h to define FALLOC_FL_COLLAPSE_RANGE if it's not in the kernel headers.
