*	[PATCH 2/2] ocfs2: Implement group add for online resize	Tao Ma	2008-01-25	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds the ability for a userspace program to request that a properly formatted cluster group be added to the main allocation bitmap for an Ocfs2 file system. The request is made via an ioctl, OCFS2_IOC_GROUP_ADD. On a high level, this is similar to ext3, but we use a different ioctl as the structure which has to be passed through is different. During an online resize, tunefs.ocfs2 will format any new cluster groups which must be added to complete the resize, and call OCFS2_IOC_GROUP_ADD on each one. Kernel verifies that the core cluster group information is valid and then does the work of linking it into the global allocation bitmap.

*	[PATCH 1/2] ocfs2: Add group extend for online resize	Tao Ma	2008-01-25	1	-0/+31
	This patch adds the ability for a userspace program to request an extend of last cluster group on an Ocfs2 file system. The request is made via ioctl, OCFS2_IOC_GROUP_EXTEND. This is derived from EXT3_IOC_GROUP_EXTEND, but is obviously Ocfs2 specific. tunefs.ocfs2 would call this for an online-resize operation if the last cluster group isn't full.
