From: David Sterba Date: Fri, 17 Aug 2018 15:28:06 +0000 (+0200) Subject: btrfs: tests: add separate stub for find_lock_delalloc_range X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9c36396c2a788facd4282a2b0646a1c4ac19847a;p=openwrt%2Fstaging%2Fblogic.git btrfs: tests: add separate stub for find_lock_delalloc_range The helper find_lock_delalloc_range is now conditionally built static, dpending on whether the self-tests are enabled or not. There's a macro that is supposed to hide the export, used only once. To discourage further use, drop it an add a public wrapper for the helper needed by tests.
