[PATCH] ocfs2: check new file size on fallocate call
When changing a file size with fallocate() the new size isn't being
checked. In particular, the FSIZE ulimit isn't being checked, which makes
fstest generic/228 fail. Simply adding a call to inode_newsize_ok() fixes
this issue.

+ ocfs2-fix-use-after-free-when-unmounting-read-only-filesystem.patch added to mm-hotfixes-unstable branch
...g fstest generic/452. After mounting a filesystem as read-only,
quotas are suspended and ocfs2_mem_dqinfo is freed through
->ocfs2_local_free_info(). When unmounting the filesystem, an UAF access
to the oinfo will eventually cause a crash.
