Hi Andrew,
After merging the akpm tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
fs/ext4/mballoc.c: In function 'ext4_mb_check_group_pa':
/home/sfr/next/next/fs/ext4/mballoc.c:3335:17: error: implicit declaration of function 'abs64' [-Werror=implicit-function-declaration]
cur_distance = abs64(goal_block - cpa->pa_pstart);
^
Caused by patch
"Remove abs64()"
interacting with commit
1a70ea8d47aa ("ext4: fix abs() usage in ext4_mb_check_group_pa")
from the ext4 tree.
I just reverted the ext4 tree commit as it is no longer needed:
