gfs2: Add missing truncate_inode_pages_final for sd_aspace
[ Upstream commit a9dd945ccef07a904e412f208f8de708a3d7159e ]
Gfs2 creates an address space for its rgrps called sd_aspace, but it never
called truncate_inode_pages_final on it. This confused vfs greatly which
tried to reference the address space after gfs2 had freed the superblock
that contained it.
This patch adds a call to truncate_inode_pages_final for sd_aspace, thus
avoiding the use-after-free.
