From 4bbe2cd12cee2a14deb2635d1240f5208a06d0c9 Mon Sep 17 00:00:00 2001 From: Amit Pundir Date: Tue, 11 Apr 2017 14:40:31 +0530 Subject: ANDROID: Skip building uid_sys_stats and keyreset drivers as modules Few Android drivers viz. uid_sys_stats and keyreset/combo fail to build as kernel modules. uid_sys_stats.ko failed for undefined "tasklist_lock", which got un-exported in commit c59923a15 ("remove the tasklist_lock export"). Quoting from the commit, "Modules have no business looking at it, and all instances in drivers have been due to use of too-lowlevel APIs. Having this symbol exported prevents moving to more scalable locking schemes for the task list.". So instead of exporting tasklist_lock again, lets not build uid_sys_stats driver as module. Similarly skip building keyreset driver as module which call sys_sync() syscall. To keep things in perspective we don't build these drivers as modules in later kernels (android-4.4/4.9) as well.
