| |
Hi Christian,
After merging the access_once tree, today's linux-next build (arm multi_v7_defconfig) produced lots of this warning:
In file included from include/linux/linkage.h:4:0, from include/linux/preempt.h:9, from include/linux/spinlock.h:50, from include/linux/lockref.h:17, from lib/lockref.c:2: In function '__read_once_size', inlined from 'lockref_get' at lib/lockref.c:50:2: include/linux/compiler.h:216:3: warning: call to 'data_access_exceeds_word_size' declared with attribute warning: data access exceeds word size and won't be atomic data_access_exceeds_word_size(); ^
Introduced by commit 6becd6bd5e89 ("compiler.h: Fix word size check for READ/WRITE_ONCE") presumably interacting with commit 4d3199e4ca8e ("locking: Remove ACCESS_ONCE() usage") from the tip tree.
