| H A D | util.c | 4f93b426 Fri May 11 10:49:30 CDT 2018 Vivek Goyal <vgoyal@redhat.com> ovl: Copy up meta inode data from lowest data inode
So far lower could not be a meta inode. So whenever it was time to copy up
data of a meta inode, we could copy it up from top most lower dentry.
But now lower itself can be a metacopy inode. That means data copy up
needs to take place from a data inode in metacopy inode chain. Find lower
data inode in the chain and use that for data copy up.
Introduced a helper called ovl_path_lowerdata() to find the lower data
inode chain.
