[PATCHSET v2.0 02/17] xfsprogs: metadata inode directories

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Add libxfs code from the kernel, then teach xfs_repair and mkfs to
use the metadir functions to find metadata inodes.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

This has been running on the djcloud for months with no problems.  Enjoy!
Comments and questions are, as always, welcome.
