Hi all,
After merging the mm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
ld: warning: discarding dynamic section .glink
ld: warning: discarding dynamic section .plt
ld: linkage table error against `hugetlb_vma_lock_release'
ld: stubs don't match calculated size
ld: can not build stubs: bad value
ld: fs/hugetlbfs/inode.o: in function `.remove_inode_hugepages':
inode.c:(.text+0x2538): undefined reference to `.hugetlb_vma_lock_release'
ld: inode.c:(.text+0x25f4): undefined reference to `.hugetlb_vma_lock_release'
Caused by commits
d56100904028 ("hugetlb: use new vma_lock for pmd sharing synchronization")
47bc61e7caf9 ("hugetlb: add vma based lock for pmd sharing")
The definition of hugetlb_vma_lock_release() is guarded by
CONFIG_ARCH_WANT_HUGE_PMD_SHARE, but the usage in fs/hugetlbfs/inode.c
is not.
I have reverted commit d56100904028 (and the following commit) for
today.
