------------------------------------------------------ From: Lu��s Henriques ocfs2-devel@oss.oracle.com 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.
