[Ocfs2-users] kernel bug 1.2.5: any ideas ?

[Sunil Mushran]

This is a build problem.

>From ocfs2 home page:
================================================================
Other Distributions: If your distribution does not include OCFS2,
you will need to download and build the sources. To build against
the mainline kernel, download the kernel from kernel.org. As OCFS2
has been included in the mainline since 2.6.16-rc1, we no longer
provide patches against it on oss.oracle.com but rather keep the
source current on mainline.

For users building from OCFS2 1.2.x tarballs with kernels 2.6.14
or later, use the following make command:

	make GENERIC_DELETE_INODE_NOT_TRUNCATES=1
