Hi all,
After merging the akpm-current tree, today's linux-next build (powerpc ppc64_defconfig) produced this warning:
fs/hugetlbfs/inode.c: In function 'remove_inode_hugepages': fs/hugetlbfs/inode.c:460:44: warning: 'hash' may be used uninitialized in this function [-Wmaybe-uninitialized] 460 | mutex_unlock(&hugetlb_fault_mutex_table[hash]); | ^ fs/hugetlbfs/inode.c:463:5: warning: 'index' may be used uninitialized in this function [-Wmaybe-uninitialized] 463 | hugetlb_vmdelete_list(&mapping->i_mmap, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 464 | index * pages_per_huge_page(h), | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 465 | (index + 1) * pages_per_huge_page(h)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Introduced by commit
