[PATCH 1/3] VFS/ioctl: Add punching-hole support to ioctl().
We're currently support two paths from VFS to preallocate unwritten extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of punching-hole should be treated as the same, this patch tries to teach file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2 is wise enough to do the rest of work;-) Signed-off-by: Tristan Ye <tristan.ye at oracle.com> --- fs/ioctl.c

[PATCH 00/42] ocfs2: Add reflink file support. V1
Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please
