Hi all,
After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:
fs/proc/task_mmu.c: In function 'pagemap_pmd_range':
fs/proc/task_mmu.c:1444:14: warning: unused variable 'migration' [-Wunused-variable]
1444 | bool migration = false;
| ^~~~~~~~~
Introduced by commit
78cff485ae77 ("fs-proc-task_mmuc-dont-read-mapcount-for-migration-entry-v4")
"migration" is only used when CONFIG_TRANSPARENT_HUGEPAGE is defined.
