From 44143583b76decf93c55b73adaf2367c22c88998 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Tue, 31 Dec 2019 13:17:48 +0000 Subject: sparse-checkout: use extern for global variables When the core.sparseCheckoutCone config setting was added in 879321eb0b ("sparse-checkout: add 'cone' mode" 2019-11-21), the variables storing the config values for core.sparseCheckout and core.sparseCheckoutCone were rearranged in cache.h, but in doing so the "extern" keyword was dropped. While we are tending to drop the "extern" keyword for function declarations, it is still necessary for global variables used across multiple *.c files. The impact of not having the extern keyword may be unpredictable.
