It looks like it's not patching very well in light of Dave's CRC 
userspace changes, and I botched the mkfs part of the merge.

For xfsprogs include/xfs_sb.h, Patch #1 has this:

+#define XFS_SB_VERSION2_NO_OQUOTA      0x00000100      /* sep prj quota 
inode */

However, in the current xfsprogs include/xfs_sb.h, there is this line:

#define XFS_SB_VERSION2_CRCBIT		0x00000100	/* metadata CRCs */

This overloaded meaning of 0x00000100 did not seem right, so after my 
failure with the finished mkfs.xfs, it was time to go back to the 
current git xfsprogs.  I'm sure that the userspace will be reworked 
before the kernel code is final.  I'll show some patience, and Dave's 
upcoming CRC code activation will probably force me to back Chandra's 
patchset out anyway.

Despite my bumbling through it all, the kernel gquota/pquota patchset 
shows promise.

Thanks!

P.S. - I applied your xfs_growfs_data_private patch, and all seems well 
so far.  In particular, there was no change in the test results from 
`./check -xfs -g growfs`.
