Subject: ocfs2: check new file size on fallocate call
Date: Mon, 29 May 2023 16:26:45 +0100

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.
